Silly question about the metal HUD

[Irishman]

I just got my first Apple silicon Mac - a nice beefy M4 Max Mac Studio running Tahoe 26.01, and paired with a LG 32” UltraGear IPS display. I’m unsure how to turn on the HUD. If it helps, I’m only trying to use it on Metal games, like Resident Evil 3 and Borderlands 3. I’ve tried to run them through the Games app and alone.

Shouldn’t there be a pull down menu option somewhere along the top of the screen????

HUD?
Is that part of the display?
Then, you would get to that through some select button on the display's remote? or somewhere on the display itself?

Not to my knowledge. I’ve seen Andrew Tsai doing so in one of his videos where he was showing how to toggle between just framerate, or something more with your Mac’s thermals, resolution, refresh rate, frame time, etc.

I’m sure that it’s just user error on my part.

Enter the following in Terminal:

/bin/launchctl setenv MTL_HUD_ENABLED 1

The post above mine is correct. It's intended as a developer-only feature so it's hidden unless you enable it via the MTL_HUD_ENABLED variable.

Enter the following in Terminal:

/bin/launchctl setenv MTL_HUD_ENABLED 1

And will that product the drop down options that Andrew had modified to add more data??

That I am not sure about as I never tried it.

I know that when the GPTK was first released, the HUD was enabled as a part of that. Its main purpose is for having a visual indication of performance. I did use it with Cyberpunk 2077 (before the Mac version was even announced), and while it did show framerate, CPU and RAM usage, I do not remember any options to toggle what was displayed in the HUD.

I did find the documentation on the Apple Developer website, which also has a link to customizing what data the HUD displays.

So I tried entering the Terminal command to enable the Metal Performance HUD and can confirm that you do get the drop down menu to add more data/information. I am on macOS 26.0.1.

Is it too much to bother you to copy and paste both the on and off commands that worked for you?

To enable the HUD: /bin/launchctl setenv MTL_HUD_ENABLED 1

To disable the HUD: /bin/launchctl setenv MTL_HUD_ENABLED 0

To enable the HUD: /bin/launchctl setenv MTL_HUD_ENABLED 1

To disable the HUD: /bin/launchctl setenv MTL_HUD_ENABLED 0

My man 😌

 

[Irishman]

Umm, is the whole command THIS bin/launchctl setenv MTL_HUD_ENABLED 1

or THIS To enable the HUD: /bin/launchctl setenv MTL_HUD_ENABLED 1

because option one didn't' work for me.


ETA: neither options worked for me. On the longer 2nd option I got this error message:

-bash: To: command not found

ETA 2: Think I got it working. I just missed the first / right before bin when I copied it.

I'll let you know once I try it out

ETA 3 HUZZAH!! It worked
