Today I saw a guide on madshrimps website describing how to correctly set up ATI Tool for my x1900xtx. I was happy and followed the steps perfectly, I disabled the ATI 2d/3d detection process, and set my core and mem speeds correctly 650/775 and my voltage setting correctly. I also adjusted my fan speeds for much needed better cooling. I then ran Oblivion and Prey without any trouble. However, when I tried to load up NWN 2 and Company of Heroes my screen goes completely white and nothing response. This only happens when Im using ATI Tool. When I converted back to the default setting, or disabled ATI these games work fine. If anyone could help me that would be great, because I would very much like to use ATI Tool, but can't if games are not going to be working. Also, Im using the latest beta version of ATI Tool. Thanks.
