This problem also happened to me in N4 and I've seen others experience it as well. For Papy and others who don't know what it is, this should let you experience it..... Do a 50% race with a full field of AI cars. Start the race and write down your FPS. After the first pit stop write down the FPS again. With about 5 laps left, again, write down your FPS. I think if you do a 100% race that the FPS would be even lower. Yellow flags also kill my FPS for the remainder of the race even after everyone has pitted and fixed damage. If after all this you don't notice a drop of about 20 fps then congratulations, you have a great system. I experienced this in OpenGL in N4 with a Gforce2 MX card and now I see it in D3D in 2002 with my Radeon 8500. Vintook

Sounds like a memory leak in the code perhaps. -John "Vintook" <[email hidden]> wrote in message news:Sv8f8.822$[email hidden]... > This problem also happened to me in N4 and I've seen others experience itas

Could be that for some reason the AI start eating fps (CPU time?) under certain circumstances. Tom Pabst reported something recently that could indicate the same - it involved strange pitting behaviour of the AI, followed by a radical drop of the fps.

The memory leak hypothesis due to some AI-related code seems most likely: if I exit and reboot the game the frame rates are back up to optimal, which rules out any chip overheating problems. If I run a race with half a field, it still slows down but not as fast. I have tried tweaking virtual memory, the core.ini memory settings, and replay memory, all to no avail. I now have 512 MB RAM in my system, of which the game (according to the memory file I have it printout upon exit) only uses 23 Megs of, for some strange reason. Very frustrating... John DiFool

I had this happen in N4. I found that it was the skid marks. I turned off skid marks and this kept my frame rates solid throughout any length race. I can't guarantee that it is the same in 2002 as I haven't turned skid marks on.

Interesting. Have you ever tried just reducing the size of the skidmark buffer?

This is one 'realistic' item that I can certainly do without to maintain smoothe frames. Smoke is another I used to run without, but finally got a card that could handle it with my GF3 and couldn't race without it now, but I can do without the skid marks for certain. Don't know if that's the problem though, didn't Tom say they (the AI) simply pitted? There wasn't a wreck involved in his problem I didn't think. Sounds like a memory or video memory leak in the game to me, but I don't code for a living...I had this problem with Motor City Online, FPS fell to nothing and then the game crashed on me. Turns out they had a bad memory leak somewhere in the D3D coding and my GF3 was choking on it after a certain length of data had been received. Tom has enough grasp on what happened he should definetly get that onto Papy's 2002 forum so someone over there can research the deal. Anyone experience this online as of yet? I am about to get our league together to start a season and it would be nice to know this wouldn't affect online racing.
I did reduce the buffer but I still found that in a 50%+ race I would get slow drop in frame rates. Joachim Trensz <[email hidden]> wrote in article <a5jlq3$81p4t$[email hidden]>...

I don't think it is a memory leak as it cleared up the dropping frame rates when I turned skid marks off. In Tom's post I thought he made reference to AI cars making repairs so therefore assumed that there were probably marks laid down. I also found that even without an accident there was enough skidding by the AI, and of course myself, to lay down extra rubber. In a 50% race at Daytona I would start losing frames about 15-20 laps in and would gradually lose up to 10 FPS over the course of the race.
