I’m using an overclock of 1067mhz. I have not needed to use force_turbo to get the games running well. I’m not using a heatsink or fan and my Pi never goes over 53 degrees.
I’m not sure force turbo is even necessary, one of the posts I read recommended it, but I’m not sure it’s helping me. I haven’t done any testing around that setting. I simply copied my OC settings from the thread I posted since there was a ton of data around stability and they seemed to be the most stable out of what was tested. So far, no issues here.
