NR2003 Graphics Tweaks

NASCAR Racing 2003 Season Graphics Tweaks

Open up your “C:/Papyrus/Nascar Racing 2003 Season” directory (this is the default path, modify as needed if installed elsewhere).

Open your CORE.INI file with Notepad and make the following changes:


Just put a 1 in front of the number. It should read:


Next, look for the:


You’ll have to calculate the amount of RAM you have. Just multiply your RAM by 1024.
(Example: 512×1024=524288)

Then insert that number so it reads:


Save the CORE.INI file and close it.

Next, open the REND_OGL.INI (if running in OpenGL) or the REND_DXG.INI (if running in Direct3D) with Notepad.

Look for the line that reads.

TextureSetSize= “number”

The “number” is what you want to replace. There is a formula for this…

( MB of video RAM) x (1048576) – ( 4 x Screen Width) x ( Screen Height) x (BPP) Bits Per Pixel, use (2) for 16bit or (4) for 32bit color.

NOTE: 16bit color will be less of a performance hog then 32bit color


The proper settings are listed here. Just look and match up your resolution with your color depth and you’ll find the answer to the formula for your TextureSetSize.

32mb video card running in 16bit “Don’t even try 32bit, it’ll be a waste of your time”
640×480= 31096832
800×600= 29714432
1024×768= 27262974
1152×864= 25591801
1280×960= 23724032
1600×1200= 18194432

64mb video card running in 16bit
1024×768= 60817408
1152×864= 59146240
1280×960= 57278464
1600×1200= 51748864

64mb video card running in 32bit
1024×768= 54525952
1152×864= 51183616
1280×960= 47448064
1600×1200= 56388864

128mb video card running in 16bit “Crank it up”
1024×768= 127926272
1152×864= 126255104
1280×960= 1246387328
1600×1200= 118857728

128mb video card running in 32bit “Crank it up”
1024×768= 121634816
1152×864= 118292480
1280×960= 114556928
1600×1200= 103497728

256mb video card running in 16bit “It’ll happen”
1024×768= 262144000
1152×864= 260472832
1280×960= 258605056
1600×1200= 253075456

256mb video card running in 32bit “It’ll happen”
1024×768= 255852544
1152×864= 252510208
1280×960= 248774656
1600×1200= 237715456

Then look for the,


Change the 8 to a 0 so that it reads:


Save these changes and close the file.

Then, in your players directory (C:\Papyrus\NASCAR Racing 2003 Season\players\<lastname>__<firstname> is the default).
Open the PLAYER.INI file in Notepad.

Look for the line that reads

[Graphic Options]
texture_quality= -1

Change this number to a value between -1 and 100 for a increase in picture quality. This will give some performance hit, but the increase in eyecandy is well worth it.

[Graphic Options]
texture_quality= 100

There’s a few more general things to keep in mind. The number of cars you draw ahead and behind will affect your FPS. The draw distance and mirror detail will affect FPS along with anisotropic filtering, lightmaps, reflections and shadows from cars or sturctures. Last but not least, Maximum Sounds Played has an effect on FPS. Lowering this to 8 seems to really help on many machines. These changes can be made under your options menu in the sims main menu screen. To tweak the most out of your system you’ll want to play around with these settings until your happy with your FPS.

You can also take control of your Virtual memory settings. Under: Settings/Controlpanel/System/Performance/Virtual memory Select “let me Specify” Ignore the Windows warning. Then set your minimum and maximum to the same setting. Let’s say, at least 500mb each or if you can spare it 1000mb minimum and maximum. This will prevent your HD from resizing it’s memory Swap file during racing and eliminate some stuttering that occurs during game play.It’s best to defrag often or even partition your HD with a 1gig partition and assign your virtual memory to that.

    Hi have a ? im running windows 7 on a 64 bit system with and nvivia 8800 640mb graphics card how do i tweek my system for that or is there a plan for this system. i have 4 mb of memory too,,ram i mean.

  2. Craig says:

    I just upgraded my PC from a dual core cpu to a quad core cpu. Since the upgrade nr2003 gameplay isn’t very good. I have 1024 x 2 MB video ram. PC Res. set at 1920×1080 32bit using Windows XP SP3 So I just set my TextureSetSize to 950861824 I came up with that number by taking the highest TextureSetSize # ( 256mb video card running in 32bit “It’ll happen”
    1600×1200= 237715456 x4 = 950861824
    Now to see if it helps gameplay.

    2132123648 This would be your final figure with 2048 video.

  4. Nate Balser says:

    oh, that figure is for (16 bit color). fyi
