Hi everyone,

I need help on how to diagnose what is causing me to have lower FPS than expected.

I can't put my finger on exactly when I started having issues as I took a break from gaming on my PC.

My spec is as follows,

Gigabyte UD3R Motherboard
Intel i7 920 D0 @ 3.8ghz
6gb OCZ Triple Channel 1600mhz RAM
Asus ATI 5850 @ 850/1150
Corsair Pro AX850 PSU

I first noticed the problems whilst playing Dirt 2, it looked a bit jittery like I was getting low FPS so I ran the built in benchmark and I got an average FPS of 23.17, with a min of 17.68, I had run this same benchmark in March 2010 and had an average FPS of 71.31, min 57.74. I didn't persue the matter too much as I don't play the game much.

Yesterday I decided to play some Battlefield Bad Company 2, and again my FPS was considerably lower than what I expected, I was running Fraps and was struggling to keep 30fps in general play but in a fire fight with grenades going off the fps would drop to 12!

What sort of tools can I run to help me diagnose where my problem lies?

My CPU is prime stable and I can run Furmark without issue too.
 
It's clearly a driver issue.

Uninstall your graphics drivers via the control panel. Download, "drive sweeper." Restart and boot into safe mode. Run drive sweeper and remove all ATI drivers. Run this until no more items appear in the list.

Boot back into your normal desktop, download the latest drivers for your card from AMD ATI.

Install it.

Re check FPS.

Let us know the conclusion.
