Maybe someone else has this issue, and hopefully, a fix. I was playing portal yesterday and it worked perfectly. Then today I started a new game and no matter what video settings I use, there are graphical problems with the game. The most obvious and game-ruining of these, is the fact that I can't see through portals. They are just black. yes, I have portal rendering set to 2, higher numbers don't do anything. Can anyone help me me with this? EDIT: yeah, i totally posted this in the wrong forum, my mistake mods.
