Recently got an 8800GT. I have not been impressed with its performance over my old 7300GT using the same cfg and settings in games even losing some fps in 1 game.
Not satisfied I started fiddling with vsync, AA and texture in nvidia control panel. I got some results I was pleased with so I started playing. Upon entering a new server it seems as though those settings were no longer applied as I had the same problem I started with.
After google basically all day Im going to start by using driver cleaner or similar and start fresh but if anyone can throw me some more ideas as it seems to be a common problem I can not find an answer to
It's probably because of the drivers, so you're on the right track with Driver Cleaner.
Did you plug in the 6pin PCI-e from the PSU in the card?if not,than there is your problem.
If nothing helps,then return the card.
Maybe the issue. I did have a 350w psu and I upgraded to this one when I got the 7300gt.
I ran driver cleaner and started fresh. After it was back up and running I ran aquamark3d and noticed in one of the high demanding areas the cpu fan slowed down :s also the original issue is still there
Try using Rivatuner to override the fan control. Your PSU whilst not the best on the market should be able to cope for a while, I ran a pair of 7900GT's on an EZCool PSU and it took a good eight months before it succumbed to power drain overload.
