I know this is old, but I still need it every so often, and I am sure other people still look for these settings every now and then too. Any other tips and tricks for better graphics in NR2003 feel free to add them. 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: [FileLRUCache] Cachesize=4194304 Just put a 1 in front of the number. It should 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 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 HUH! WHAT THE? 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" 640x480= 31096832 800x600= 29714432 1024x768= 27262974 1152x864= 25591801 1280x960= 23724032 1600x1200= 18194432 64mb video card running in 16bit 1024x768= 60817408 1152x864= 59146240 1280x960= 57278464 1600x1200= 51748864 64mb video card running in 32bit 1024x768= 54525952 1152x864= 51183616 1280x960= 47448064 1600x1200= 56388864 128mb video card running in 16bit "Crank it up" 1024x768= 127926272 1152x864= 126255104 1280x960= 1246387328 1600x1200= 118857728 128mb video card running in 32bit "Crank it up" 1024x768= 121634816 1152x864= 118292480 1280x960= 114556928 1600x1200= 103497728 256mb video card running in 16bit "It'll happen" 1024x768= 262144000 1152x864= 260472832 1280x960= 258605056 1600x1200= 253075456 256mb video card running in 32bit "It'll happen" 1024x768= 255852544 1152x864= 252510208 1280x960= 248774656 1600x1200= 237715456 Then look for the, AnistropicLevel=8 Change the 8 to a 0 so that it reads: AnistropicLevel=0 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.
