frame rates and gpu load

post #1 of 3
Thread Starter 
i've been noticing something odd, and i don't know if it's just me...

on my 4780x2, whenever playing a game or running 3dmark benchmark, the lower the frame rate, the less the GPU's are loaded. and the higher the frame rate, the closer to full load they become.

i'm using Everest to monitor GPU loads and fan speeds and core temps on my G15 LCD. in Crysis, for example, if i look out at a vast scene (with very high settings), like the bay at the beginning, i'll get around 20FPS. the GPU will barely be working and the temps and fan speed reflect this. but when i look straight up at the sky, i'll get around 60FPS and i can hear the fan turn all the way up and i can watch my gpu load and temps soar. it doesn't make sense.

it would seem to me that your GPU would work the most when the frame rates are lowest, since it's obviously having trouble rendering or why else would the frame rate be so low?

has anyone else noticed this? and not just on a 4870x2.

This is a symptom of the issues I've had with my 4850 setup. The only thing I can think of is its CPU bound - doesn't make sense to me though

EDIT: Just seen what CPU you've got - that should definitely NOT be an issue!

well it is, however, now with the new 8.10 RC2 drivers and running crysis wars in DX9 with enthusiast settings, i'm getting pretty much full GPU load most of the time. it still dips down a little bit when the frame rates drop. but it does it worse in DX10 mode.

anyone else have a theory?
