This has weighed on my mind for a bit.  For Aces High, what is the appropriate resolution for a 22" screen?
I'm currently running at 1650x1050.  What would be the next logical step down?  
1650X1050 runs fine at 16X anti-aliasing.  But at 16Xq my fps goes down to around 40 when I get near land and kills the "reality" factor..
