Do you mean if if you can use a higher resolution than the game sets? For
Direct3D games this can work, but for DirectDraw it is going to fail.
Direct3D games which draw only untransformed vertices pass coordinates in the
range of [-1.0 ; +1.0], which later get scaled to viewport coordinates. With
a different viewport we can trick the game into doing that. It will get
tricky when the app draws transformed vertices(which have screen
DirectDraw games access the screen directly by using coordinates from 0, 0 to
with, height. If wine makes the surface bigger the rendering will just end up
in a corner. The best thing we can do is to scale it, but that is what your
monitor does if you set a lower resoltution.
So you *may* be able to trick the game into using a different resolution, but
this will have to be a per-game hack and can't be done in general.
