Open up your C:/papyrus/Nascar4/Nascar2002 or
Nascar2003 racing season directory. These ini.file adjustments will work with
all three sims. The performance gain hasn't been as great for 2003 as it was for
2002 but it'll still get you some frames. Look for your core.ini and open it
with notepad or just by double clicking it. Look for the line that reads,
[FileLRUCache]
Cachesize=4194304
Just put a 1 in front of the number, So it'll read
[FileLRUCache]
Cachesize=14194304
Next, look for the
[Memory]
Maxblocksize=131072
You'll have to calculate the amount of RAM you have. Just multiply your ram by
1024
Example: 512x1024=524288
Then insert that number so it reads,
[Memory]
Maxblocksize=524288
***We have heard that on some computers
Nascar 2003 will lockup and/or crash to the desktop when using values above 512
on your ram to configure your [Memory] Maxblocksize .
Save the core.ini file and close it.
Next, open the rend_ogl or the rend_d3d file, Whichever your running the game
in, OpenGL or D3D.
look for the line that reads.
TextureSetSize= "????????"
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
HUH! WHAT THE?
I listed the proper settings here, Just look and match up your resolution with
your color depth and you'll find the answer to the formula for your
TextureSetSize.

Then look for the,
AnistropicLevel=8
Change the 8 to a 0
AnistropicLevel=0
Save these changes and close the file.
Then, In your players directory. Open the Player file
Look for the line that reads
[Graphic Opitions]
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 Opitions]
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.
