Ok I was screwing around with the games graphics by running a .bat file, but now they're stuck and I can't get them to go back to default. A lot of shaders and normal mapping and other effects are gone now and even doing a reinstall doesnt fix this. Any help would be great.

A good place to start would be to copy / Paste your .bat file so we can see what it did.

It was a .bat I used for the demo my friend sent me cause I wanted more fps, so I don't know what most of these mean.
