I'd like to share some feedback on technical part. Aside from usual and well-known problem of frequent TDR crashes on DX12, I have textures on units and buildings corrupted. Here is the sample (hosting deformed image, but corruption is easy to see on factories):

Also, moving light sources, most notably missiles, are flickering all the time. Probably, that's due to interference of some time-dependent algorithm (like temporal AA) with lag - since the second HD7970 of the crossfire went down, my rig is lacking firepower.
