PC still lagging a lot with "low GPU thread priority" and very low RBS/RPP settings

I can't make RT leave resources for internet browsing when rendering with RT CUDA. Even with "low GPU thread priority" checked and 32/8 for RBS/RPP, my PC still lags heavily. It's a simple product shot on a white background so the scene is not even heavy at all. I'm using nightly 3.57.01.

Try lowering to 32/1 for example to see if that helps.

No, didn't help. I forgot to mention that I'm using RT CUDA as production renderer, not active shade.

[savage309]

I have to double check, but I think we made it work only in Active Shade mode, just to make sure that somebody rendering in production would not render longer because of having forgotten of that option.

Ah, not good. Usually I try to work on other stuff while I render. Maybe this setting shouldn't be exposed in production mode so at least users won't be confused that it does something.

Yep, I agree. I put a not in the bugtracker for that. Thanks for the pointer!
