Quickly enable/disable the Metal 3 Performance HUD as outlined in MrMacRight's excellent video.
Requires macOS Ventura 13.
As opposed to enabling the HUD for each individual game or application, this script sets the env
variable MTL_HUD_ENABLED globally to apply to any Metal 3 context.
Add as a bundle through Antigen:
antigen bundle timkurvers/metalhudmetalhud on
metalhud off
metalhud status
