When I play the game with 3DFX glade setting, windowed mode, the game starts in a small window (like with Direct3D setting), but when I click on the full screen, it ends up like this:

With Direct3D this works ok, but I can see that my game is considerably 'grainier' than the streamers...and they are using 3DFX.
Anyone got ideas to make this work? The gfx card that I have is GT 970.
Tried messing with most of glade settings but nothing helps.
