@miniZ It appears the high CPU usage is on my rig with RTX 2060 cards. I happens with both the recent beta and the newest release.

On my rig with GTX 1080s it has normal CPU usage.

On a positive note, the latest beta has fixed the issue where GPU usage would stop randomly for short periods of time.

Thanks for your work!

$@X: remove your current driver from your system with 2060 and install 431.60 driver. I think you will not have that problem with high cpu usage after this.
