I have noticed with two cards now that my 2d clock will kick in during Guild Wars. At first I thought it was my video card but it has done it on two cards at stock speeds. Now even with my 2d clocks my card handles Guild Wars but thats not the point whats the deal? What it does is my 3d clock will start no problem but randomly will switch to a 2d clock. I've truned off the adaptive power etc... I wonder if this is drivers or what is the issue anyone?
