Hi!
The Metal rendering API is 120FPS regardless of whether vsync is set, and all Samples are like this. Under Windows, it can run to 1300fps. Metal API I use is macbook pro.OS is macOS Sonoma 14.0.

I found the reason, because macOS versions are different, metal API settings vertical synchronization variables are different, need to set displaySyncEnabled is false.

SyncdisplayEnabled doesn't seem to solve this problem completely. It still runs 120 frames when rendering, and then automatically changes to a non-vertical synchronization frame rate after a while. And it seems ogre's metal rendering isn't as efficient as opengl?
