Bug Report Low framerate in Studio Mode

[Paul-Tahoe]

According to a friend, who happens to work at the mother ship (apples new headquarters), QuartzDebug switched to Metal around the same time this broke. Everybody has been using a stackoverflow article on how to create a private api to turn off v-sync. That method broke with Mojave. The good news is there is a public apple api to turn off v-sync that can and should be used.

displaySyncEnabled | Apple Developer Documentation

A Boolean value that determines whether the layer synchronizes its updates to the display’s refresh rate.

BTW, the same engineer says using the work around with Quartz Debug is fine. Basically, the api is doing the same thing as checking the Enable Vertical Sync box.

This issue should be resolved in OBS Studio 25.0.6. Please give it a try and let us know if it's working for you!

Upgraded to OBS Studio 25.0.6 and it now worked fine in Studio mode, previous version was 24.0.6 which of course had the issue in Studio mode.

Yea. 25.0.6 seems to fix the issue. Thank you.

By fixed, do you mean I can stop using Quartz Debug to manually turn off Enable Vertical Sync?

Yes, Studio Mode should work without any special changes or tweaks.
