Nascar 2002, Patch slowdown :( Help...

Hi Guys, Can anyone help? After I loaded in the new Nascar 2002 1.1.0.1 patch, when driving with the cockpit view, I get a terrible slowdown. Down to about 30 fps. It used to run alot better than that before the patch. I had completly uninstalled the sim, and then reloaded it, and then loaded the patch, so it isnt because of it overiding the previous install. Even though I only have about 30fps in car, when I watch the replay from any other camera, I get a good 60fps, which is quite nice and smooth. Any advice on how to overcome this, as I cant play the sim like this :( This is my main equipment Athlon 900mhz 256 pc 133 sdram 30gb drive gforce 2 gts pro 28.32 drivers Thanks Ben.

Try copying rend_d3d.dll from the original CD to your installation directory. Hey, and some people are so skint they're lucky to get 25fps in a race ;) -- Joseph Birr-Pixton

While its true that coping the file will work you really should be running openGL with your Geforce card. With the patch taking advantage of texture compression you should have better graphics at higher speeds. MadDAWG

This problem with the patch must be specific to Nvidia cards because the patch caused no slowdown on my Radeon 8500.

I know D3D does texture compression, but pre patch NR2002 did not do it in OpenGL. This would cause a mipping down of the textures to get them all to fit in the cards memory. This mippig down is why alot of people thought OpenGL looked worse than D3D. So now that NR2002 supports texture compression in OpenGL there is no reason to run a Geforce based card in D3D. As far as ATI goes I have not messed with them since my Rage Maxx Fury card a few years ago. MadDAWG

Sounds like you've got vsync enabled - the patch does this. You need to download a tweak for your vidcard to be able to force vsync off in D3D. Can't remember what said tweak is called - "coolbits" or something. A google search will give you plenty hits on the subject.

NVMAX and Geforce tweaker are two other options. MadDAWG

I only get the option for 16 bit color with OpenGL. Is this correct, or do I need to play some more "driver roulette". As an aside, my main problem driver-wise, is finding one that is a) fast for gaming, especially NR2002 and b) won't crash PowerDVD. TIA, Gerald

I think OGL will only use the same colour depth as your desktop, try changing that to 32 bit true colour. -- Ian P <email invalid due to spam> "Gerald Moore" <[email hidden]> wrote in message news:[email hidden]... > "MadDAWG" <[email hidden]> wrote in message news:<[email hidden]>... > > So now that NR2002 supports texture compression in OpenGL there is no reason to run a Geforce based card in D3D. > > I only get the option for 16 bit color with OpenGL.

I don't know what happened, but I went back to try it again, and it did have 32 bit color listed. I don't recall switching desktop color depth, but that seems to be the likely explanation. OpenGL gives my system (AMD 1.4 TBird, Gainward GF3 "Golden Sample") about a 50% boost in framerate. Gerald "Ian P" <[email hidden]> wrote in message news:<acb6sb$gho$[email hidden]>...
