Il2 1946 on steam resolution issues.

[MadBlaster]

look for the file config.ini. this has your game settings for video, audio...etc. you will likely have to tweak a lot of these parameters to suit your needs.

for resolution look for this section:

[window]
width=1152
height=864
ColourBits=32
DepthBits=24
StencilBits=8
ChangeScreenRes=1
FullScreen=1
DrawIfNotFocused=0
EnableResize=0
EnableClose=1
SaveAspect=1
Use3Renders=0


there is a guide somewhere (like mission4today) that explains what all the settings do and what happens if you change the numbers (e.g., 0 to 1, etc.)

for the mouse i think these:

[rts]
ProcessAffinityMask=2 good idea to run on one core only
mouseUse=1
joyUse=1
trackIRUse=1
DisableIME=0
locale=
JoyProfile=3

[rts_mouse]
SensitivityX=1.0
SensitivityY=1.0
SensitivityZ=1.0
Invert=0

[MouseXYZ Config]
RealTime=1


Also, I recommend open/gl instead of direct x. Also, SLI, I don't think that works for this game. So that could be screwing up your video output if it isn't set right.
