That's the official story, without the Widescreen mod, have you tried it?Ok, so i finally figured out what i could do to fix the problem, for anyone having the same issue. It was really quite simple, after fooling with anti-aliasing and other options a thousand times over i finally went back and noticed that the resolution i was using was not supported by the game.
I have not, but i will look into it. I just wanted to make it work without any mods applied, as they could potentially just cause more problems in the end, with files being changed and all that.
