I just want to to play Doom 3! Hi everyone. I have a Radeon 9550 256MB. I basically just want to run Doom 3 with no lag. I just downloaded ATITool 0.26 and tried to run Core Test and Mem Test. The first thing I did was unlock the 9550 card, then I proceeded to run Core Test. After it got to about 430, it crashed and I got an error message from CCC. So I wrote down 420. Then I ran Mem Test and when it got to about 280, the screen got all weird with strange multicolored transparent blocks everywhere. So I stopped it and wrote down 280. I then used those settings and saved a profile. When I ran Doom 3 it looked sort of shitty. It seemed like it had no AA. Also, tiny black blocks showed up around occasionally. When a cut scene ran, the blocks were everywhere. I have 1GB of RAM and 1.80 GHz. What do you people recommend I do? Thanks.
