I have a Windows 10 64 PC and 2 GPUs.
Just recently I received 2 large tasks which is fine but there is a problem.
For some reason these 2 tasks do not play good with TThrottle.
I can run each independently and the Throttle is 50% with nothing running on the second GPU.
When I run both together or even one with a Collatz GPU task then the Throttle goes up to 99% very quickly.
In other projects I can comfortably run 2 GPU tasks without any issue.
I think there must be something special in the way these tasks run on windows that causes Throttle to misbehave.
I did inquire to the author about Throttle and 2 GPUs and within his reply he said,
"As it can't throttle the actual GPU it slows down the feeder CPU process."
Does anyone have a workaround for this. I Use Nvidia 980 cards.
Primegrid is not a new project and I find it hard to believe this is a new problem but after reading through the forum I could not find anything that helped.
I am happy to support but do lack a little in the expertise ;)
Here is the example of the 2 tasks,
Here is the image showing when 1 (large) Primegrid task runs the Throttle is 50% (it is the same, 50% Throttle, when I choose either of the Primegrid tasks shown in the first image).
