Don’t know if this is a known issue or only I have it, but I’m having hard time running tech alpha with my new AMD card R9 390. I had GTX 750 Ti which is by all means inferior to R9 390 and game runned at constant 30 fps with medium settings at 1080p. Now, however, whenever I open game it starts windowed with with 1280x720 resolution on medium preset and it is not even close to smooth experience - I get 30-40fps. If I try to make it full screen, then I get black screen.
Maybe its just optimization issue but it sure is very strange to see such thing.
