GPU bottlenecks

Last response: in CPUs

I have an fx 6300 @4.3GHz stable, and in some scenarios in BF3 i see the GPU usage is not near 100. I look at Core temp, and the CPU load isnt even near 100%, thus leading to the bottleneck. How can i fix this?

You need to give us more info such as the rest of your system specs, GPU resolution etc.

there will always be a bottleneck somewhere.

v sync is disabled i assume?

yes it is disabled

I see a lot of **** around here, but BF3 will never take full advantage of 6 cores, it is simply not programmed that way.

The GPU consists of many different operators, dealing with different parts of the graphics. For example if shaders or memory bandwidth is limited, raster operators would sit idle, waiting for input. Therefore you can not expect it to be fully used.

If you have vsync enabled without additional framebuffers your GPU will often sit and wait, because it is only allowed to deliver certain amounts of frames per sec.

If you are having issues with framerates, make sure your drivers are up to date, or perhaps you should have invested in a better GPU.

okay thank you
