Changing AA settings requires that the D3D device be recreated. Therefore, only A6 can do that, otherwise it couldnt draw anything later on.
I’m not much of a programmer but I don’t think we need GS to change AA. When I change AA settings manually (via graphic card software) it shows in my game made with GS.
So...I just have to find a way not to do it manually and then start my game.
I’m sure there’s a launcher or a little exe somewhere on the web I just haven’t found it jet. I’ll check that Wintermute launcher to see if that is useful for GS.
