I've encountered a problem with Halo when I upgraded from a 9800 Pro to a 6800 GT. I lost the cloaking effects in halo!! I believe this is because the game detects Nvidia hardware and assumes it is an FX and defaults to lower precision and removes to "taxing" effects. How do I get those effects back? I've heard you have to fool the game into thinking its running on ATI hardware by changing the card ID, but how do I do that?
