Hey, I just got Doom 3, and I installed it and started playing it. The game says the graphics should be set to high, at 800*600 resolution, with everything in the advanced menu on but vertical sinc and antianalyzing. I changed the resolution to 1600*1200, and it still plays fine, I just get a lot of sharpies, the backrounds look semi-pixelated, and it just looks alot worse than I had expected, not nearly as good as HL2. I turned on vertical sinc and antianalyzing, same problem. I turned it up to ULTRA with everything turned up to max. Aside from a little lag, it only looks slightly better and still is nowhere near HL2. I'm gonna try High with 1024*768, and vertical sinc and antianalyzing off and see what happens. If anyone knows why this is happening, please tell me. My GPU is a NVIDIA FX 5500 256 mb.
