CPU not being completely utilized under Bad company 2?

post #1 of 16
Thread Starter 
This is very weird, I must say. I have an AMD Phenom II X2 550 BE @ 4Ghz, 4GB DDR3 1066 @ 6-6-6-15-12-1T, and an AMD Radeon HD 4870 1GB (GDDR5, 256bit). When under load (everything on High, No HBAO/V-sync) my CPU only tends to use 70-80% of my CPU. Now, when recording BC2, my CPU tends to use 82-92%.

I want my CPU To be completely utilized, so when I record I can get 50FPS Ingame, while I record @ 60FPS, compared to the 35-45 FPS Ingame and recording @ 60FPS. I usually get.

My RAM Is only gone up to 55-60% in usage too. my GPU Is, quite obviously maxing out @ 99%.

There's your problem, your GPU can't render any faster and is bottlenecking. Could pick up another 4870 for dirt cheap or go with a better card

edit: just looked at your mobo and since you only have 1 PCI express slot Crossfire is out. You would need to get a new gfx card to increase your frame rate at your current settings

Your video card is not bottlenecking. However, it is weak. Your CPU is fast enough so it doesn't get all used up.

HMM.... Your saying it's my GPU? Isn't my CPU Responsible for pumping FPS itself out, or is that a GPU's thing? I know the CPU is responsible for the rendering (Graphics quality).

Now, from what I understand is that most guys with E8600's @ 4.1Ghz see a bottleneck in their CPU, but why am I not seeing one in mine?

The CPU pushes the frame to be rendered then the GPU actually renders it. Whats happening is your GPU can't render the frames as fast as the CPU can feed them so the CPU sits idle for a small portion of time

Some of that may be that you have DDR3 1066 RAM whereas the guys with E8600's would be using DDR2 800-1066 which has a slight performance difference.

Oh... I get it now

EDIT: So, Overclocking what part of My GPU will render frames faster? Core or Memory?

Yep, thats why it would be silly go put a GTX580 with and old P4 and conversely an ATI x1600 with say a 2600k or 990x

Both Core would be the place to start since that is the part that actually renders the frame. What is your current Core clock at?

I think overclocking the core will give best result (shaders too?) but you could overclock the memory too
