Hey guys,

I just tried battlefield 3 with my gtx 680 sli and i get an average of 60% GPU load on both GPU.... with everything ultra... i just dont get it. why wont it use more gpu power to get a stable 120fps?

Did you overclock your CPU, put the game on a fast drive?
Typically there's a bottleneck somewhere if your utilization won't go to 100%.

Same problem here , but I have a lower ranked Cpu than you.

I have the same problem on 301.42 WHQL drivers. Might be a driver issue as my cpu isn't even maxing out. Kind of frustrating. I was playing on ultra usually around 60+ fps on most maps but now its dipping into the 30's every now and then. Had to drop it to high @ 1080p

Have you tried to lower the settings to low/medium too see if the fps increases?

sounds like a driver problem for the 680

Set the profile to Prefare max performance?

I get full utilization here with the 300.83 driver!

1920x1080 / 70Hz

Where do you see full utilization in this screenshot ? i think your gpu usage is the middle number in % ??

It's never going to use almost 100% of your cards...it doesn't need to...

??? it needs too if it dips in the 80-90fps when my cpu isnt even capped and my video cards are at 60%.... its a driver problem for sure :\

I don't run with VSync off, i get 70fps at all times which is my fresh rate on this monitor.

qgshadow · 06-06-2012, 04:22 | posts: 14

Yeah i got a 120hz monitor

Uh, you have ~50% GPU usage on both cards, 1 card would give the same FPS.

Shadowdane · 06-06-2012, 12:05 | posts: 646 | Location: Virginia

Hmm yah something is up... It seems to be always forcing VSync no matter what setting I use. I set it to 640x480 60hz and it was capped at 60fps with VSync Off.

I forced VSync off in driver and game and it made no difference.

BF3 was patched last night, maybe they missed a bug?

i get this with 680 sli in windows 8 on the 301.42 whql

Try forcing V-sync off and see if that spikes the GPU usage upwards.

I already tried this both in game and in the driver. Forcing VSync off and the game is still locked to my refresh rate.

I even tried 640x480 with VSync off and its locked to 60fps.

Was there a solution to this?
I just got a second 680 and still cant get 120fps. Gains are not too great over one card.

I don't think this problem is 6 series exclusive. I get big frame rate drops with no gpu usage increase, started happening after the June patch, it's the worst on Oman.

Shadowdane · 06-26-2012, 20:04 | posts: 646 | Location: Virginia

Yup i saw framerate issues immediately after the last patch, I even rolled back to 300.84 which was flawless 60fps with VSync before the patch.

Now it struggles to maintain 60fps. I think DICE messed up something in the last patch. Hopefully they will update the game to fix this!!

snowdweller · 06-26-2012, 21:10 | posts: 492 | Location: Sydney

I updated my drivers to 304.XX and started seeing dips in FPS. My usage though is still around 80-100 on my 580s so I'm assuming its a 6 series and driver thing. Can you try any other drivers?

EDIT: This is with 2560 res and 4xMSAA in game and enhance 4x in NVCP with all high quality. I'm V-synced to 60 except big maps from afar the FPS drops pretty bad but usage is always up there.
