I don't have another pc to try it on except the family laptop but people are always on that anyway so theres no point...
I opened that file, here it is: [Begin Graphics Config]

Hopefully that helps :) Thanks for still trying to help!
Maybe try making a copy of that cfg (just so you have a backup) and replacing the contents with someone else's, to see if there is a problem in there (just until someone more knowledgeable on the cfg can check over the actual data).
Here's mine, if you wanted to try it (also contains my multiplayer data XD) - just remember to keep a backup of your one...
