Topic: GPU acceleration increasing CPU load

When i use GPU acceleration, my CPU load would be higher. Shouldn't it lower my CPU percentage?

GPU acceleration should free CPU from intermediate frames calculation. You can see it as lower CPU load or as lower CPU frequency.

1. What CPU do you have?
2. What CPU frequency in both cases (with and without GPU acceleration)?

Re: GPU acceleration increasing CPU load

i have a i5 2500k oc'ed to 4.7ghz
HD 5770

without GPU, i get 55-65%
with GPU, i get 60-70%

I think you have different frequency. 4,7 Ghz is max. Check it by CPU-Z or in System info window.

I don't use madVR and when i use or not use GPU, it will be 4.7

and for some reason, it happens again
