I have a few questions. First is what Windows 10 version are you on? If you have the 1511 version and didn't patch, your system will over heat like crazy with the Compressed memory glitch.I guess it's time to report back. Alright, overall, I'm disappointed in the 2016 model (in comparison to the 2015 one). Basically, here are the things. For the first few minutes, the new Macbook perform about 50 % to 100 % better than the 2015 model. However, after 10 minutes (or less) or play, things get coarse. I'm getting about 10 % more on the 2016 model but that's it. Frame rates are a little bit better on the 2016 Macbook than the 2015 one. I suspect that the thermal throttling kicks in so there's minimal difference in GPU performance.
Skyrim is a nice exception though. Since the game is not very demanding in terms of action/cpu, it maintains its 30 fps on high. But overall, this is not the case. It seems like the thermal envelope on the 2016 is the same as on the 2015 one.
Also did you have the m5 or m7. My m7 did the opposite, it was actually the same FPS or laggy for the first few minutes, then leveled out higher than the 2015 model. It kept better FPS during an hour of play and cooled down compared to program launch.
