I'm having some issues with my GeForce4 Ti4600 and Half-Life 2. The game itself runs smooth enough, but I'm getting these weird boxes all over the areas, where steam or dust particles are supposed to be. Here's an example:
I've upgraded to the latest drivers, checked with Nasty File Remover to ensure that all my drivers were the latest version, and I'm not overclocking my card, nor is it overheating. Any suggestions?
