Hi Marco,

No that's not exactly correct, it's only in certain circumstances that there is a big difference at the API level, such as with overhead from smaller batches.

MoI already does a good job of batching things up and so it's not likely to be affected really at all by such things.

It's not likely that there will be any noticeable difference in Moi after targeting Metal. The reason for MoI to target it does not have any thing to do with performance, it has to do with compatibility with future OS versions.

I've also seen some developers say that Metal had more driver bugs for them than OpenGL until pretty recently. But hopefully it will be easier for them to maintain the Metal drivers than the OpenGL ones from here on out though.
