I've been using RT for years. Now, I have a GTX 260 with a 179 series driver and RT 2.10. I have overclock and fan profiles that kick in (and out) when I start (exit) a game based on the D3D "acceleration flag". All works amazingly well. My problem is that months later I go back to modify my single overclock profile and the settings will not stick. Not only will they not stick, the profile gets reverted to default clocks. I then tried creating a new oc profile and updated my launchers (or whatever needs changing) and all I get are default clocks. It appears that I can no longer save a profile with non-default clocks. I change the clocks, hit the Apply button and re-save the profile or create a new one. Sometimes when I leave that panel, you can actually see the clocks change back to defaults right before the screen draws the main panel. I uninstalled(completely) and then reinstalled RT 2.10. No effect. I then uninstalled completely and installed RT 2.11. No effect. I then uninstalled and went through the registry and deleted every entry with the word RivaTuner and Unwinder in it. I then installed 2.10 again and everything was working fine again. Any ideas about what's going on?
