Battlefield3 ATI 5970 issue

post #1 of 12
Thread Starter 
BF3 is not utilising both cores on my 5970. I've tried other games and they're fine.

Both Afterburner and GPU-Z report around 1% load on one core and near 100% load on the other???

HELP!

What drivers are you running? Im having no problems with the 11.10 Preview 3 drivers and 11.9 cap4. It seems to be hit and miss right now for alot of people.

You can also try alt tabing when in game so it goes to window then alt tabing back to full screen.

AMD is always putting out preview drivers to try to fix things in between full release drivers. Some are better then others, But ive always had pretty good luck with new drivers.

Hear is the link to the drivers http://support.amd.com/us/kbarticles...eDriverV3.aspx

You should use 11.10 Preview 3 + 11.9 CAP4, your card should be then utilizing both cores and probably maxing out the game or pretty close mantaining +60fps.

If you have stuttering, I suggest you to disable HT from your i7 on the BIOS, also, use Antialiasing Post on HIGH, but do not use Deferred Antialiasing (MSAA) as it kills performance and offers not much better AA than Antialiasing Post does. Also, for ambient occlusion, try SSAO instead of HBAO, a lot smoother too.

I'm using 11.9 NO CAPs and Afterburner is showing that BF3 is using 99% on both GPUs in my 5970.
