Is there a best practice for a Metal app to determing its current frame rate (or
if it is meeting the target frame rate)? The goal being to dynamicly adjust the
work being done, to keep the frame rate at an acceptable level.
Background: I have an AppleTV Metal app who's frame rate is dominated
by the work done in a compute kernel. The work done in the kernel was tuned
based on 4th gen AppleTV performance when it was developed, and now
I'm updating it to dynamically take advantage of the higher performance
of the 5th gen.
Initial testing indicates compute kernel performance on 5th gen
is about 2.5 to 3 times that of 4th gen. Does that seem reasonable
or should I expect more?
