Hey guys so I fixed the minimizing problem I think by going into properties for GHA.exe, then the compatibility tab and ticking "Disable full screen optimizations" This is in windows 10 so I'm not sure if you have the same option in windows 7,8.
Also to Mohkerz. First off thank you! Second I have tested the game at 1920x1080 and it seems to work fine and looks fantastic!
Question though, when using a 360 controller what buttons are the strum bar? Or do you not need the strum bar when using a controller? Does this mean if I use a guitar controller that the strum bar is not needed and wont work properly?
