re the perfect mode stuff, its an ati issue. i'm nvidia so not my expertise. as suggested use the search, its a well known problem and can be fixed.

re the resolution, no you will not see it in any menu, it willl just boot up in that res, once you've changed the conf.ini and started the game. Thats it, no further action is necessary. do not change the res in game, do not use the il2 setup after the conf.ini changes.

[window]
width=1920
height=1200
ColourBits=32
DepthBits=24
StencilBits=8
ChangeScreenRes=1
FullScreen=1
DrawIfNotFocused=0
EnableResize=0
EnableClose=1
SaveAspect=0
Use3Renders=0

make sure ChangeScreenRes=1, in fact just copy all those settings, with your res.
