My PC specs:
Intel 4790, two AMD R9-280x GPUs, nVidia GTX 1070
Running Lunatics optimized apps.
Radeon driver is V16.6 while the nVidia driver is V375.95.

Yesterday I replaced an AMD HD7850 with the nVidia GTX 1070, and since then, my keyboard and mouse have been jerky while using the PC to web surf, read email. All tasks that used to work easily.

I have the CPU limited to 84% CPU, which was lettings 6 CPU and 6 GPU tasks run fine, when I was using three AMD cards.

Task manager shows between 84 and 100% cpu utilization, and when I snooze the GPU tasks, the CPU utilization drops to to 80-81%.

It seems that the GPU tasks are not using 0.04 CPUs, that the BOINC manager indicates, and it also does not appear that the GPU CPU utilization is not capped at the 84% limit in preferences.

I'm not sure if this is a result of mixing nVidia and AMD cards, or what.

Any one have any suggestions on what I can do?

Thanks!

Update: I probably should add that the nvidia is configured for Cuda, not OpenCL. Not sure if that matters or not.

Update:

This definitely seems GPU related.
I can configure the CPU limit to drop to 4 CPU tasks, and 6 GPU tasks.
The overall CPU % is between 68 and 70% and the mouse and keyboard are still slow, making using the computer nearly impossible without snoozing the GPU processing.

I am thinking that it is a rendering issue with the GPU.

I have the nVidia attached to my primary monitor, and my second monitor is attached to one of the AMD 280x cards.

I have been searching the forums for anyone running into anything similar and haven't seen anything that wasn't from 6 or 7 years ago.
