Does your monitor support free sync for VRR as you might have to turn it on in the monitor menu. I seem to remember having to hunt for this as it was not turned on by default.I'll probably just do that then, the power drawn issue is absolutely ridiculous, how it hasn't been fixed yet is beyond me, but as long as I grab a USB C device capable of 2k @ 60fps should be all good and shouldn't hog system resources & cause any slowdowns really should it?
Knowing me i'd drown my card!
