BF3 GPU usage low? - Page 2

post #11 of 17
Happened to me too. Here's what happened:

On 11.9 CAP1:
Pretty bad performance, about 30% each and sometimes 50% each

Installed 11.9 CAP4:
Amazing performance, each GPU was between 93-99%
Then the day after performance sucked again and it was constantly 50-60% each

Today, installed 11.10 CAP4:
Performance was the same (still sucked, around 50-60% per GPU)

Did a complete driver wipe with ATIMAN, then reinstalled 11.10 CAP4:
Performance was pretty good (90-95% per GPU)

Then I noticed I had a bad install because CCC wouldn't open, so I reinstalled 11.10 CAP4 without doing a driver wipe. I have yet to test it.

@op,you didnt say if you have Vsync enabled or disabled.

If you had Vsync enabled then i would expect to see exactly what is in your screenshot and theres no problem at all.

If you DO have Vsync disabled then yes,you have an issue.

Exactly this mention^. Vsync ON will not let the cards be at full load; basically setting an FPS cap.

Consider overclocking your 930 to hit 4.0 GHz to prevent any bottlenecks you may encounter. Your mobo and CPU are a great pair for OCing; similar to my rig.

I had an issue with my GTX 470 dipping from 99% down to 5% every few seconds. I went in and made the BF3.exe file a high priority and for the past couple days it has stayed at 99%.
