I'm using GPU passthrough for over 4 years now w/o any issue. You may confuse this with igpu passthrough (which was unusable in the past).

I figured out, that the problem was with nvidia-39xxx, using 340 instead and everything works as expected. GPU load is @98% and CPU load @10%.

Edit:
It seems that with opencl-nvidia-390xx the card stays in lowest power mode and some more issues (like it still could have a higher GPU load even in lowest power mode)
As I read through the internet I see that other ppl having issues with 390 and "older" cards as well.

Edit2:
It's just another bug in nvidias proprietary driver, at least there's some work done on OpenCL support in nouveau driver this summer, maybe we can get rid of this nvidia driver shit later on this year.
I keep it with Linus "NVidia, fuck you!"

Yes this system is virtualized, but performance is at 95% @ everywhere else. What about the low GPU utalization?

According to https://www.svp-team.com/wiki/GPU_Compatibility a GT430 should be capable, but GPU accerlation is way to slow. I recognized that if disable GPU accerlation CPU usage is around 40-50% and GPU Utilization is @ 30-33%. If I enable GPU accerlation CPU usage drops to 10% and GPU Utilization is below 10% and video playback is hard desynced and stuttering

(Video Engine Utilazation is always @0%)

Something wrong with my system or is the information about the GT430 just out of date, and the card is to slow for SVP 4.x?
But I'm absolutly confused about the CPU/GPU utalization. Why is GPU utalization higher if I disable accerlation, and why is GPU utalization just around 10% if accerlation is enabled (no wonder it lags/stutters/desyncs as hell).

Best regards
