Geforce Now 120fps WebRTC on Safari 17.5 for macOS

Agreed, it could be tied into a permission prompt. 

Also do note that safari and chrome for macOS support 120fps webRTC. Although, it seems safari for iOS, iPadOS, and visionOS only support 60fps webRTC.

Also note: 120fps WebRTC for macOS works even with “prefer page rendering updates near 60fps” is set to on. 

I will attach an image of GeForce Now streaming at 120fps (see top right of image) on safari 17.5 for macOS. I have the “prefer page reading updates near 60fps” set to on in this test. Even though it says "120hz stream" in the top right, with “prefer..60fps” enabled it is clearly only 60hz. I turned off the feature flag and it was a very noticeably 120hz. Either way, 120fps WebRTC works for safari for Mac, but not any other device. Although, above 120fps (240fps, 360, 480, etc) does not seem to be supported for safari for Macs.
