I can’t seem to get the game to run in 1366 x 768, my screen’s max resolution.
Other games run at this resolution fine (Crysis, Bioshock 2, Borderlands, etc)
I ALREADY TRIED TO EDIT THE CONFIG file, but it just resets to 1280x768 whenever I launch the game.
I own the game for Steam, and downloaded it through Steam
I have Windows 7 64 bit
Compatibility mode won’t work
I have the latest drivers.
Any help would be appreciated! I’m desperate! :’(

Have you tried running in DirectX 9 mode, rather than DX10? I had the problem with Devil May Cry 4 (which uses the same engine)
I’ve actually been running it in DirectX 9 mode; running in DX10 makes no difference either. 
I have been able to get the higher resolution, but it only works in Windowed mode for some reason…Whenever I switch to full screen, the resolution randomly drops to 640x480(?). Weird…
