With this driver in nVHardPage dont work correct Direct3D tweaks and refresh rate fix. Overclocking and OpenGL tweaks work OK, but for Direct3D you need do this: From old drivers (31.00) copy file NVQTWK.DLL to your windows\system32 directory (C:\WINDOWS\SYSTEM32). New drivers has some new features, so wait for next NVhardPage release. Matus Paculik - creator of nVHardPage
