Hi, I just received a rMBP and was gaming on w10 via bootcamp. 750m driver is up to date. Problem is the frame rate was not stable and was dropping so low for a moment which renders the game unplayable. Decided to watch gpu temps and clocks while gaming and I've found 750m gets too hot and clocks down and up which causes freezing/lags because it constantly changes it clocks. Since 750m was running at lowest clocks possible and starts to fluctuate when it's hot, I tried manually maxing out fans before starting the game. Yeah with pre-maxed out fans maybe clocks were a little bit higher than before at first 5 minutes, but the problem still persisted as clocks are always fluctuate and rendered the game unplayable. My first thought of the reason was the insufficient 85w power adapter. But I don't understand that because back in 2012 I could play games on 2012 rMBP with 650m without any issues. Frame rates on 650m was always stable as rock. Fans were kicking out of course, but everything was stable. I did not check the clocks of 650m back then but I'm sure it was not changing itself constantly. Anyone experiencing the same issue with 750m ? My rMBP is a mid-2014 with 2.5 ghz. I've tried both power plan setting balanced and high performance, high performance forces cpu to run at turbo boost speed and temps get hot too quickly. Balanced power plan adjusts cpu speed so it is used only when needed. Can I force the 750m to run at stock speeds constantly ? It supposed to do run at stock speeds, not fluctuate. I do not even want boost feature, I just want stable stock clocks when gaming so games would be playable. There is the readings of gpu-z program showing the clocks when running Dota 2 : As we see it fluctuates constantly in game, only when I press alt+tab and go desktop it locks to stock clocks. It does not pass 80 celsius and stays around 70-75 in-game.
