OpenCL Rendering mode multitasking

Post by redhot2 » Thu Feb 01, 2018 9:27 pm

Hi guys. I've got burning quetion for you.
Is there any trick to lower opencl performance while rendering scene?
It makes browsing net and email unbearable. Even songs played from yt or player slutters.
Also it would be nice to render and use sketchup/blender at same time.

Or maybe I should think about another machine for work? So this is basicly my question for you:
How do you reconcile this two things?

Im using mostly path tracing OpenCL for quicker, only visual scenes (on 1050Ti)

You'll need a separate GPU for your main display. The key is not using your display GPU for rendering - then you'll be able to surf to your heart's content.

The 1050 Ti is pretty much the Pascal version of the earlier Maxwell-based 750 Ti, which is our minimum supported spec GPU. So it's already going to lag a little bit, because we're aiming for faster GPUs such as the 1070. On the plus side, those lower end GPUs can overclock like crazy, you can try that to squeeze quite a bit of extra performance out of it, which will also manifest as less lag.

Many CPUs (e.g. all Intel desktop CPUs since 2nd Gen Core) have onboard GPUs that are very competent for normal desktop usage, so unless you're planning to do some gaming you can switch to using this GPU for display and pretty much leave it like that. Otherwise, my advice would be to get a dedicated GPU for display, which can be quite inexpensive.
