Metal slower than Legacy OpenGL

using a MacStudio with an M1 Ultra, Metal does not seem to do anything good, its rather jittery and lags behind the mouse when panning and rotating the view on normal non complex geometry. I have read several reports that it should actually improve the performance compared to Open GL. What is happening? I would say Open GL feels almost normal, almost because the only positive difference i see in regards of Metal now is that it seems to handle a viewport filled with multiple entities better than Open GL, BUT something Open GL handled well enough before all those changes (looking at Apple and McNeel)

Metal is still very much a work in progress. We almost have all of our code ported to Metal, and hope to start in on performance tuning in the coming months. It’s still not quite time to start judging Metal.
