So I've been playing Witcher 3 for about a month now on my rig (i7, 8gb, gtx 760 2gb, win 10 x64) and on and off i've been getting odd performance issues. I can set the game to run on high and ultra settings and it would do just fine, with decent 50+ fps. But after a while it would slow down a lot, I don't have an fps counter but it feels like 15-20 fps at times. So I'd try lowering the settings, even going as far as turning EVERYTHING off or putting on lowerst settings, lowerst resultion etc. It wouldn't help in the least bit. The only solution was to quit, wait about 15 min and restart it.

So I started doing some reasearch and got a GPU-Z monitor. I run it while playing the game, and I noticed that as soon as the temperature goes over 80+, the Performance Cap section tells me that the card is getting capped because of thermal output. It does that and alternates with V-Rel, which is the reliability voltage.

Since then I tried everything, I went into my case cleaned out all the dust and such, cleaned the fans, made sure the case is sealed good. Just updated my driver to the latest release and even use the setting reccommened by GeForce Experience for that game. And I still seem to get the slow downs.

So the next thing I'm thinking of trying is trying to max out the gpu fan somehow, because GPU-Z is telling me that even at 83C the fan is running at 64%, which I don't get why but in any case, is there a way to manually set the speed. I googled it obviously but the only thing I could find was the setting in the nVidia control panel. But the control panel that came with the latest driver doesn't even have that "performance" section, so I'm kind of running out of ideas. I'm even contemplating moving my box from under the table to my window sill, but that's like the last resort.

Any suggestions?

Thank you Mark, that worked perfectly. Just tried it, set it to curve to 100% at 78C and it seems stable enough even on 1080p. Slight lag, but nothing like before. I went back to CPU-Z to check, and I'm not getting a thermal cap anymore. Now it's almost entirely v-rel. I played the game for 10 min and it was entirely capped by v-rel, I'm assuming that's because the fan is using more voltage now, right? I can't really shell out for a new power supply atm, but do you think disconnecting one of my dvd/bluray drives would help? Thanks again!
