Bad GPU utilization in Battlefield 3 (5970)

post #1 of 4
Thread Starter 
Hi.
Before I overclocked my i7 to 4 GHz I used to have really crappy utilization (like 30-40% on each core), however after I did I had almost constant 99% on each core. Haven't played for a while now though, and suddenly my utilization is really ****. It has been for a lot of different drivers, and it sort of acts like this:
If I have everything at low @1600x900 I get around 60-65% on each core, and my fps goes from 131 (where I cap it) to 80-90 depending on the map.
If I put up some of the graphics, like shaders/AA etc. the utilization goes up to 80-90%, but my FPS remains the same anyhow.

The problem with the drops from stable capped 131 to 80-90 is the mouse responsiveness, which changes everytime it drops. Is there anything I can do to get 99% on each core again? I just want to be able to have 131 stable fps with everything at the lowest.

Current drivers: 13.6 Beta 2 and 13.5 CAP 1 app profiles.

That's mainly because in most maps with 64 players you're limited by the CPU and not the GPU.

They kinda broke the game's performance in some maps (Specially Back to Karkand maps) a few patches ago. frown.gif

Try dropping the Mesh quality (And restarting the game), that should help a bit with GPU usage.

I have everything on low, mesh quality too. This is happening on the smaller maps also, not just the 64/128 player ones. I don't have 100% CPU utilization either though :/

You don't need to have 100% usage on all cores, maybe 1 thread is maxed, it's poor optimization from the game.
