I played around with the settings and I'm able to play all the way up to medium at 800 x 600 perfectly smooth with all the advanced options on! Way better then I expected, and it looks great.

One major problem though. The flashlight beam dosnt show up. So I can't light anything up. Trying to play without it, but I keep dying cause I can't see any of the enemys untill there actually hitting me. I have a feeling its cause my graphics card dosnt support whatever feature they use to make the beam, that might be the reason it was considered unsupported
