Need for Speed: Most Wanted Tweak Guide

In-Game Settings

The following are the main in-game settings for Need for Speed: Most Wanted which can be changed to alter image quality and performance. Each is covered in detail under the relevant section. I note the image quality and performance impacts of each setting, however keep in mind that obviously the impacts will differ depending on your particular system hardware. Make sure to view the descriptions and associated screenshot/animated comparisons carefully and find your own balance of image quality vs. performance.

The best way for you to arrive at the optimal settings on your system is to read the descriptions below, then experiment by using FRAPS, a free utility which shows the number of frames per second (FPS) in the corner of the screen. Adjust your settings and note your FPS - the higher your FPS, the smoother your gameplay will be. You'll notice in the screenshots below, you can see the FRAPS counter in the top left in yellow digits. Fraps is also handy since it allows you to take screenshots of gameplay and even record demos.

To access the main game options, scroll to the Options icon at the bottom right of the screen, and click on it or press Enter. Under the Options section, there are five sub-sections: Audio, Video, Gameplay, Player and Controls. Each is covered below:


Volume Controls: The five sliders here control the various volume levels for the main audio elements of the game. Adjust according to your tastes - none have any performance impact. Moving a slider to the far left to disable a particular element will not give you a performance boost.

Interactive Music: This setting controls the generic game background instrumental music, not the EA Trax songs. For example, when being chased by police in the Roadblock Challenge, the background music will become more tense, but if you are evading police and in Cooldown mode, the music will ease up. There may be a slight performance impact due to the extra CPU usage when this is enabled, but it is for all intents and purposes negligible, so set to suit your taste.

EA Trax: This setting controls whether the tracks performed by various artists are played throughout the game. No performance impact as such, set to suit your tastes. See the Conclusion section to find out more about the game music.

Audio Mode: The main options here are Stereo or Mono, and although Mono may provide slightly better performance on low-end systems, there should be no reason to choose anything other than Stereo.


On the main Video settings screen, you will see a 'Level of Detail' slider and a Resolution setting. I strongly recommend that you ignore these and manually adjust the various Advanced elements below for optimal performance and image quality. To access the Advanced graphical menu, click the Advanced icon at the top right, or simply press the number 2 on your keyboard.

Note, as the game suggests, adjust your monitor's brightness (or use you graphics card's control panel) by looking at the twin EA Games logos in the center of the screen and following the written instructions.


Resolution: This setting controls the pixel width by pixel height of the image on the screen. The higher the number of pixels on the screen, the more detailed the image but the lower your performance. Choose a resolution which is not too high, as resolution has a major impact on performance in the game.

Full-Screen Anti-Aliasing: Full-Screen Anti-Aliasing (FSAA, or simply AA), is a method of smoothing jagged lines on the screen. The higher the slider is taken here above the far left, the higher the sample rate of antialiasing used, and the smoother jagged lines will appear in the game. You can read more about FSAA and see examples in my Simple Antialiasing and Anisotropic Guide. In NFS:MW moving the slider one notch to the right from the far left provides an instant reduction in the jaggedness of lines, however it also brings with it a major performance hit. Further moving the slider to the right doesn't noticeably improve image quality, but further reduces performance. I recommend that if you need the FPS, you set the slider to the far left (disable AA). If you really want to smooth out jagged lines, only move the slider one notch to the right, as any higher will severely drain performance for little or no visible image quality gain. Also make sure to set your Antialiasing settings in your graphics card's control panel to 'Application Preference' to minimize conflicts with this setting.

Texture Filtering: This setting affects the way textures (the 2D surfaces of all 3D objects) appear in the game. Once again refer to my Simple Antialiasing and Anisotropic Guide for more details and graphical examples. This setting does not change the actual texture resolution or overall texture quality as such, it only implements texture filtering which affects the crispness of textures as they fade into the distance. For an animated screenshot comparison which demonstrates the impact of the various levels of the slider, click this link: Texture_Filtering.gif (432KB). Look closely at the cracks in the road in the far distance, the edges of the sidewalk and the white lines on the road - at higher settings they appear much sharper in the distance. However as you can see by the brick wall to the left, the actual texture quality remains the same throughout. The performance impact of Texture Filtering is not as dramatic as that of antialiasing, however at the Highest level it can reduce FPS noticeably on older/slower graphics cards. Once again, make sure to set your Anisotropic Filtering settings in your graphics card's control panel to 'Application Preference' to minimize conflicts with this setting.

VSync: Vertical Synchronization (VSync) is the synchronization of your monitor and graphics card's abilities to draw a certain number of frames per second (or FPS) on the screen. This is referred to as the Refresh Rate, and is measured in frequency per second (Hz). If this option is enabled (i.e. set to Yes), your maximum FPS cannot exceed your current refresh rate at your chosen resolution, and more importantly your overall FPS will be reduced. For this reason it is strongly recommended that you set this option to No. The only down side is that if VSync is disabled, you may notice some image 'tearing' - that is the bottom and top halves of the screen may appear to tear apart slightly at times. This causes no damage to your monitor, but if it really annoys you enable VSync. Once again, I want you to understand that with VSync enabled, not only is your maximum FPS capped, but your average FPS will also fall. For example, with VSync disabled, if you get 37FPS in a particular section, with VSync enabled you will get 30, as VSync rounds down the FPS. Verify this for yourself using FRAPS and you'll see what I mean.

World Level of Detail: This setting controls the level of detail in the surrounding objects in the game world, such as trees, mailboxes, poles, etc. The best way to see the impact of the various levels of this slider is for you to look at this animated screenshot comparison: World_Detail.gif (438KB). Look closely at the trees in the distance, and the sign to the right. As the level of detail rises, more trees are visible, and at one notch from the far right (High) almost everything is visible, but the sign only appears at the Highest setting (slider to the far right). The performance impact of this setting is most noticeable at the Highest level, so Medium or High would be a good choice for most people. The precise impact depends to some extent on your CPU power, and to a greater extent on your graphics card to draw all those additional details. The biggest impact of this setting will be felt when going through forest areas, and also when combined with the Shadow Detail setting. At High for example there will be lots of trees as well as lots of shadows, which will slow down most systems.

Road Reflection Detail: This setting controls the level of detail given to reflections on the road's surface. I didn't find any significant performance or visual quality difference whatsoever when changing it on my machine from lowest to highest. In theory when at the lowest setting (slider to the far left), the surrounding objects will not reflect on the road's surface, and when set to the highest, all reflections will show. Set this to one notch from the left if you want a good balance of visual quality and performance, otherwise in most parts of the game there is no significant image quality or performance impact that I can see.

Shadow Detail: This setting controls whether shadows for various objects are shown, and to what extent. To better see what this means, look at the screenshot comparison above. With the slider to the far left (Off), virtually no shadows are visible, save for the basic car shadow. At the middle slider setting (Medium), the car casts a more accurate shadow, but still no shadows from the trees. With the slider to the far right (Highest), the trees cast detailed shadows on the car and the surrounding surfaces. The performance impact will vary by system, but in general selecting the highest setting will see lots of slowdowns in areas with lots of detailed objects, such as forests and complex city scenes and/or lots of vehicles. This is made worse if you have a high World Detail setting. The best performance is seen at the lowest setting, and since visually the Medium setting is not much better, disable shadows is highly recommended to most people for gaining a great deal of FPS and avoiding slowdowns.

Car Geometry Detail: This setting controls the number of polygons used to draw the vehicles in the game. When set to High, the car models are as detailed as possible, with lower performance compared to when set to Low. However I couldn't see any major differences between these two settings, and in general the cars still look quite good at the Low setting.

Car Reflection Detail: This setting controls the way in which vehicles reflect the surrounding objects. Look at the screenshot comparison above, noting the reflections on the hood. When set to Low, no detailed reflections are shown of the surrounding buildings, yet when set to High, these are reflected accurately in the hood, and on other parts of the car. For the most part this setting has variable impact depending on which view you use (i.e. if you can see your own car or not), and whether other vehicles are in view as well. The more vehicles are visible, the greater the impact on your FPS, which can be quite noticeable on some systems.

Car Reflection Update Rate: This setting controls the rate at which reflections are updated on the car models. That means the higher this setting, the more smoothly reflections move over the body of the car; the lower the setting, the more jerky reflections seem to be as they are reflected around the car. Firstly if you've lowered the 'Car Reflection Detail' setting above, this setting will obviously have less of an impact. However if you've left that setting at High, moving this slider further to the right will increase the realism of the reflective surfaces of vehicles in return for reduced performance, depending on how many vehicles are visible on screen. The screenshot comparison above shows the difference between the lowest and highest setting, because anything above the lowest setting looks fairly much the same in static screenshots. The best way to check for the impact of this setting is to use the Close rear view of your car, and as you drive around, note the smoothness or otherwise of how reflections move across the car's body.

Rain Effect: This setting doesn't control whether rain is visible or not. It controls whether the 'rain effect' - namely droplets of water on the screen - are visible or not. If set to On, whenever driving through rain your screen will show small droplets of water which distort anything visible through them. If set to Off the rain will still be visible, but those droplets won't appear on the screen. The performance impact is not major for most systems, however some people may simply prefer not to have distortionary droplets on the screen.

[Page 6] In-Game Settings (Pt.2)

Over Bright: This setting controls the rather strong 'bloom' effect shown in the sky for example. It simulates HDR (High Dynamic Range) lighting. It does not control the overall lighting quality of the game, which is controlled by the 'Visual Treatment' setting below. The screenshot comparison above shows what I mean by this - when set to On, you can see that the light at the end of the tunnel is overly bright and intentionally glary. However when set to Off, while you can see that the lighting at the end of the tunnel is not so bright, the tunnel lights and the remaining glare of the car's tail-lights etc. remain the same. The major impact of this setting is primarily in reducing or increasing road/sky glare. Performance-wise, the impact depends on your particular graphics card, and for most systems there shouldn't be a major impact, so set to suit your tastes.

Visual Treatment: This setting controls the overall 'atmospheric' image quality of the game. It is controversial in that some people like it (like me), and some people hate it. The game developers have purposely designed the lighting and color of the game to be very rich and almost photo-realistic in places when 'Visual Treatment' is enabled. However, it is a stylized image quality which may not suit some people. Fortunately the designers have provided this setting for you to enable/disable this feature, and the concurrent image quality impacts are shown in the screenshot comparison above. As you can see, with this setting at Low the colors and lighting are much closer to that of other games, and when set to High they take on a completely different characteristic. This setting also controls the various motion blur effects as well. Choose whichever you believe is more realistic to you, and note that the performance impact will vary depending on your graphics card's age - older graphics cards may get a noticeable reduction in FPS with this enabled.

Note: If you only want to disable certain elements of the Visual Treatment (such as motion blur) but not lose all the appearance of High Visual Treatment, see the Advanced Tweaking section.


Autosave: When set to On, your game progress will automatically be saved as you win/lose races and challenges. If set to Off, you will be prompted to save at certain points, and you will also have to remember to save your profile regularly if you want to keep things updated.

Game Moment Camera: If set to On, particular circumstances in the game will be slowed down and played from a third-person detached camera angle. For example certain car jumps, running through certain objects, etc. may trigger this behavior. If you find this distracting or annoying, set this to Off.

Car Damage: If set to On, your vehicle will show the damage and marks from collisions throughout the game. If set to Off, no damage is shown and the car remains pristine. This can improve performance slightly, but obviously reduces realism.

Rearview Mirror: If set to On, whenever you race in Hood or Bumper view your rear view mirror will be visible at the top of the screen. There may be a slight performance impact on some systems from enabling this option.

Units: Determines whether you use the Metric or Imperial scale for gauges shown in the game (e.g Miles vs. Kilometers).

Race Map Mode: This setting determines whether the Race Map is disabled (Off), shown in the bottom left corner and rotating to always correspond with the way you're facing (Rotate), or shown but static (Static). Set to suit your taste, disabling the map may gain a small performance boost.


Transmission: Determines whether you race with Automatic (Auto) or Manual transmission in the car. If set to Manual, make sure to check your key bindings under the Control section to assign a Shift Up and Shift Down function to the relevant keys.

Camera: This determines by default where your viewpoint is when driving your vehicle. The options are Close, Far, Bumper and Hood. Close and Far show your car from close rear or far rear positions. Bumper shows you the street-level view devoid of any of your vehicle's details. Hood view shows only your hood. Choose one which suits your driving style, but note the performance impacts: Close provides the greatest performance hit, since your vehicle takes up a large portion of the screen, and vehicle details, reflections etc. can reduce performance. Far is next in terms of performance impact, while Hood provides moderately good performance since only the hood is visible, but if 'Car Reflection Detail' is set to High this can reduce performance. Bumper provides you with the best performance since no part of the vehicle is visible.

Gauges: If set to On, your speedometer/tachometer gauge is shown in the bottom right of the screen. If set to Off, this is removed and might provide a mild performance improvement. However this is an important part of the display and generally should not be disabled, particularly as it also shows your Nitrous and Speedbreaker levels (See below).

Race Information: This is the display at the top right of the screen, showing you your current race position, race time and % completed (depending on the game mode). Enable or disable to suit your tastes, has no performance impact.

Split Time: This setting controls whether a split time is shown at certain points as you race around a track. Enable or disable to suit your tastes, has no performance impact.

Score: This setting enables or disables the display of your cumulative score in modes in which you earn a score. Enable or disable to suit your tastes, has no performance impact.

Leaderboard: This setting enables or disables the leaderboard display at the top right of the screen, showing you your relative position against the other players, and their times. Enable or disable to suit your tastes, has no performance impact.


This section determines your key/mouse bindings for various controls in the game. Make sure to go through carefully and adjust to suit your playing style. In particular note the following commands which you may not be familiar with:

Speedbreaker: This is a new feature to the Need for Speed series, and works much the same way as 'bullet time' in Max Payne, or the 'SlowMo' function in F.E.A.R. - it slows down time for a short period allowing you to think through your manoeuvres more carefully and with more precise control. Make sure to assign an easily-accessible key to this function. The orange Speedbreaker bar is shown at the top of your gauge and regenerates over time.

N20: This is the Nitrous Oxide key, and in many game modes this allows you to use a short burst of Nitrous to boost your speed. Bind it to a handy key and keep in mind that the green nitrous bar is shown at the bottom of your gauge, and regenerates depending on how fast you are going.

The next section provides details on the Advanced Tweaking possible in NFS:MW.

Need for Speed: Most Wanted Tweak Guide

[Page 7] Advanced Tweaking

This section covers the ways in which we can adjust the image quality and performance in Need for Speed: Most Wanted outside of the In-Game Settings, as well as a couple of ways of assisting in resolving problems with the game.

Registry Editing - The Basics

The tweaking in this section involves editing values in the Windows Registry. This can be a relatively risky procedure, so if you're not familiar with Registry editing, I strongly recommend you read the Registry Editor section of my TweakGuides Tweaking Companion which covers how to edit the registry safely, as well as going over the terminology used in this section.

All of the Registry entries listed below can be found under the following key in your registry:


Note that registry entries which relate directly to a setting which can be easily and fully changed from within the game are not covered below - you should adjust these in the game and not here. The following are the major advanced settings you should experiment with:


This setting appears to control the amount of memory NFS:MW allocates for caching game-specific information. On my system this value is 906289152. Since 8 bits = 1 Byte, 1024 Bytes = 1KB, and 1024KB = 1MB, dividing this number by 8388608 (1024x1024x8) should give you the amount in MB that the game is using for a cache. On my system this appears to be around 109MB (I have 2GB of RAM). Raising this value to 300MB (2516582400) appears to slightly smooth out gameplay performance on my system. Experiment with values up to around half your system RAM to see if it helps smooth out your framerate.

CD Drive

This entry should point to the current drive you have your NFS:MW CD in. If you are having disc detection/authentication errors then change this to the correct drive letter here.


This setting controls the motion blur effect, such as when you trigger Nitrous, as well as when you are moving at high speeds. Disabling this setting can make the image quality crisper and also improve performance particularly on older machines. To disable this setting set the value to 0, to enable it set it to 1.


This setting controls the particle system in the game, and if set to 1 particle effects (such as smoke from spinning wheels) will be enabled. Particle effects can be particularly punishing on some systems, and if you notice that your FPS falls noticeably in situations where there is lots of visible smoke, dirt or explosions, setting this to 0 will switch off such effects in return for a performance boost.


This key records the current version number of the game. You should check to see if you have the latest version (See the Patches & Mods section of the guide). If for some reason you find a patch has not installed properly, you can change the version number here so as to fool the patch into thinking it's an older version and hence reinstalling properly.

Install Dir

This should be the correct path to your current installation of NFS:MW. If you are having game errors such as 'Speed.exe not found' then make sure the path shown here is correct.


I am unsure what this setting controls. The default value on my system is 84 (Decimal) / 132 (Hex).


I am unsure what this setting controls. The default value on my system is 73400320, which if the value is in bits equates to around 9MB. Raising this value seemed to have no significant impact on my system, however I suggest you experiment with values of twice your current value to see if this further smooths performance.

That covers all the known advanced tweaks for NFS:MW. If you have more accurate descriptions than those listed above and/or find more ways of tweaking the game which aren't covered here or in the in-game settings section, please Email Me with the details. New tweaks will be included here for all to share, and those discovering them will be given full credit.

The next section provides some important general information about NFS:MW and brings the guide to a conclusion.
