Have you tried mine already?Are the mouse coordinates correct? I tried multiple programs for borderless windowed fullscreen and the mouse pointer coordinates where always shifted vertically - probably because the window had the title bar at the top but nothing at the bottom, thus it is "uneven" when borderless.
DX11 would be appreciated very much. No point in playing in DX9 if you can do DX11.
My launcher should fix said problem by updating the game's viewport after removing the window borders.
But it apparently doesn't work for everyone.
I'll be making a DX11 version once DX9 is working reliably then.
Would have gone DX11 from the beginning but it always had huge input lag until the current patch finally fixed that.
