Someone had mentioned in an earlier post, which is now buried, that ATI Catalyst 12.2 and up conflict with GPU Tweak now. The Asus devs should look into this. Also, I think it's noteworthy that the x64 version of GPU Tweak always installs in the x86 program files folder regardless.
i also noticed that it installed the x86. I downloaded 2.1.7 and as soon as i go to open it it pops up search for solution online or close program, so i uninstalled it and reinstalled 2.0.6 and it works perfect like before. so i'll stick with this version(2.0.6) for now cause it seems to work with my setup..
