So this may be a long shot, but whatever:
Been having an issue for several months with my ASUS R9 380 STRIX 4GB on Win 10 x64 where (while gaming) video output will go black except for (sometimes) a frozen mouse cursor and audio still playing for 5-10 seconds, then comes back. Timing seems completely random - sometimes it will happen twice in under a minute, sometimes I can go several hours with nothing. Seems to happen most often while playing Final Fantasy XIV (full-screen or full-screen windowed), but has also happened with Overwatch, Civ V, and Guild Wars 2, among others. Only using one monitor at 1920x1080 connected by DVI.
I have tried: Doing clean driver installs with both DDU and AMD's clean install option, rolling back to earlier drivers, using the latest drivers, all latest Windows updates and various game updates installed. Also tried raising the GPU power limit 20% or so, seemed to possibly help briefly, but may have been a coincidence. Tried Clockblocker last night briefly, haven't had a chance to use it for long enough yet to see if it makes a difference though. Updated to the latest Relive driver package last night also (clean install option), didn't appear to change things at all, had the issue occur another 3 times afterwards.
Basically looking for the "best" advice at this point, if there is any - should I try rolling back drivers again, keep using Clockblocker, another post elsewhere mentioned changing a global AA setting, etc.? I am not willing to try reinstalling or downgrading Windows completely in an attempt to fix this, as while it's annoying, it's not THAT annoying.
Is there any chance that AMD is actually planning on fixing this issue, or am I out of luck since it's a 2-year old card at this point?
