AMD User Experience Proxy and handle leaks

This is an odd fellow here. As you can see in the image below, AUEPMaster has 157k handles. Yesterday it had over 1 million but I failed to capture a screenshot before reboot. This hasn't impacted game performance as far as I can tell, just an annoyance.…

I’m saying it now with hopes that it sinks in: Donald Trump cannot take any oath of office until he is granted amnesty for breaking the last one he swore. That’s just straight up in the Constitution. 2/3 of each House. That’s the bar.
