Using GPU lags computer

post #1 of 5
Thread Starter 
First of all, I can fold at full steam on my sigrig and still use it for surfing and other general tasks. I understand that it is far more powerful than the computer in question but still...

So, on a secondary computer with a phenom II X4 and a Radeon HD5670, when I set the client to use the GPU the whole computer lags making it practically unusable. In this scenario I have it set to use 2 cores of the CPU and the GPU.

Is this normal?

You mean you fold on AMD with CPU + GPU, but only on 2 cores full load (gpu + smp2) and you left another 2 cores for GPU + web surfing? This way yes, But gpu driver will affect load on cpu. check cpu usage when running GPU folding only and compare with different drivers.

A lot of people with lower-end GPUs report noticeable lag when folding on the GPU. That's a large reason why v7's default behavior is to only GPU fold when idle.

Does this lag occur even if nothing else is running? Some people realized that certain programs use a lot of GPU time without it being obvious, which causes a lot of conflict with folding due to the lack of scheduling for GPUs. In particular, most web browsers implemented GPU acceleration.

Yeah so basically its setup to fold on the GPU + 2 cores of the CPU leaving 2 cores for whatever else. During this the CPU load is around 80%.

The lag is most obvious when I open a we browser or another program... When I open a browser the mouse drags slowly across the screen and everything is obviously struggling to process. I suppose it's just the nature of the beast with low end GPU's? I didn't realize the GPU played such a significant role in general tasks.

Try to disable hardware acc in the browser, in FX it's in preference and advanced.
