Hi, thanks for answering.
It should be shift according to this video https://www.youtube.com/watch?v=zGsr0Lt_iqs, but it does nothing for me, the game just starts normally. I can see logo and then black screen with red Ironseed cursor. I have Win 7 and 10 in dual boot. The problem is the same regardless. of OS.
Oh, and there is no sound as well, in logo or in game, dunno if it should be that way.
I tried to play with aspect ratio settings, as people recommended. tried scale on display, no scale etc. Does nothing for me, sorry.
