So played around a little and I don't think my current comp can handle it..or I'm running at min specs. Like how it's mostly the same though...with a few minor tweaks. Def worth 9.99 though.
Usually you can turn textures to max with no fps impact. this will make it look a lot better. I turn everything else off (except texture steaming (always should be on)) like shadows ect for gameplay reasons.
Also be sure to check out the recommeded mods as they make a huge difference in gameplay.
