After some minutes of play of San Andreas, the game becomes very slow, FPS drops to below 10 while before it was about 30.
Speedfan shows about 60 degrees C for the card when this happens (but this problem persists when I cool the card with a fan and the temp drops to 50).
Now this PC recently had it's mobo replaced to fix some memory issues. The memory issues were gone but there were speed issues so the processor was replaced. This seemed to fix the speed issues for normal applications (like browsing and word processing) but not gaming.
With this setup:
2GB DDR2 RAM
ASUS P5KPL AM SE motherboard
Pentium D 3.2GHz
Geforce 7600 GS Silent
I should be able to run GTA San Andreas right? No, I could only get reasonable performance on 800*600 (32bit) with everything on low.
So yesterday I went looking and found that sometimes disabling 'enable write combining' could help for slow games. This seemed to work, because now I am able to run it on 1024*768*32bit with everything on the highest setting at good FPS, until a few minutes in the game when the FPS drops.
Any ideas why this happens and how to fix it?
