fps issues

Halfway through my 2nd stint at Le Mans my gfx got screwed and fps was not brilliant .....

I figured this was because my pc was probably running hot
or something as it had been on for over 24hours ........

Was just wondering if you turn off replays would this increase fps as i always have replay
set on full quality and always on ....

I Have recently purchased a 9800gt xfx which ran great when i first got it had everything
in the display turned up to FULL OR MAX ........
My pc has about 6 casefans in it but i have noticed the fps seems to be struggling again just recently
so ive found myself winding the display settings back to medium and high just to help the fps .....

Any Ideas .....

Yes for such long race I suggest you switch the "auto save replay" off. After too long a consecutive time on a server this gets too much for any PC I think. Certainly is the case for mine, and I have the same GFX as you .
