Choppy framerate in UPBGE

Why is UPBGE choppy when I start it in Material/Rendered mode? I am using an M1 iMac, with an x86 version of UPBGE 0.31, so it shouldn’t have this issue at all, since M1 Macs are meant to be powerhouses in terms of performance. Seems to happen with a No-Collision armature object, which I assume might be a bug…

Show the profiler,

Also M1 is using funky openGL drivers,
There is a metal viewport on the way I guess.


Also, what is a “metal viewport”?
