IL2 1946 Triple Head FPS

[chonker]

Hello,

I've just recently started venturing into the world of flight sims, I've bought IL2 from steam after watching some videos on youtube, it looks really good. I am struggling to get it to work properly on my 3 screen setup.

after a lot of searching and fiddling around got the game launching and displaying across 3 screens by setting my left monitor as the primary display and editing my conf.ini as follows:

[window]
width=4800
height=1200
ColourBits=32
DepthBits=24
StencilBits=8
ChangeScreenRes=0
FullScreen=1
DrawIfNotFocused=0
EnableResize=0
EnableClose=0
SaveAspect=0
Use3Renders=0

[GLPROVIDER]
GL=opengl32.dll

However I'm experiencing horrible framerates (2 or 3 frames per second), I've got a pretty modern rig, intel I7 @ 4ghz with a GTX480 so it doesn't seem right.

Am I missing something obvious?
