Uhm no, the first time i started it up it was like that, even the starting screen was like it. I've validated my files, and re downloaded Half Life 2. still that same.
I just started playing half life 2, and everywhere i go, all walls, flooring, roofs etc are rainbow coloured. It was trippy at first, but now when i try to shoot, because of all the light colours, and a lot of white colours, i can't see my crosshair, and it's just getting annoying. Help please? :|
