I got this to work last night. Seems that I had to activate the profile twice for it to work as the first time it just made the clocks jump to 400 MHz. The second time they went to 875 MHz on both GPUs (monitored with RivaTuner GPU sidebar gadget) and stayed there for the duration I played Psychonauts. The game felt much smoother as a result of the higher clock speeds even though the framerate was the same (v-synced, 60 fps). I then selected the Default CCC profile I'd made after exiting the game to restore the original clock speeds. So thanks a thousand times over for that tip. Can I apply this overclocked profile to Psychonauts using my RP profile and then restore it the same way, say, using the scripting feature? If so then how do I do it please? Thanks in advance.
