The GPU is 2 days old, I just received it.
I had a GTX260 MaxCore 55 before that, and the performance increase isn't as I expected.
BF3 still runs bad on Medium and above at 1680x1050 with no AA or AF or Post-whatever or HBAO.
AC Brotherhood runs *almost* smooth on Max settings, AA and AF off, and it uses DX9.
For BF3, I've tried both Win 7 and Win 8 RTM, both 64 bit versions.
Should I not expect more performance than I am getting with such a GPU, or is my CPU too slow? Do any games even use 4 cores these days, besides BF3?
What I wonder: why is the GPU load at 75% and even 65% at times? Should it be doing the best it can to maximize FPS?
I used a tool that shows me the following info ingaame:
CPU Core load for each core an each thread (2 cores x 2 threads, 4 threads overall)
CPU Load is consistently above 80%, sometime reaching 92% or even 97%.
GPU Load is anywhere between 48% to 95% at extreme cases.
You'd think it's a CPU bottleneck (and aybe it is) but there are occasions where FPS drops from a nice 48-75 to as low as 20 FPS, even midflight which doesn't reneder that much anyway, while the CPU load is around 85% and the GPU load is around 50%.
So the CPU Cores aren't completely being used, so why does the GPU decide to settle for just 50% load, resulting in a sluggish 20FPS?
