Hi, this update is great! I've been waiting for HEVC video on macOS for literally years! It looks like you had to switch to the Metal hardware decoder to do it, which is a great choice.

However, it's caused a problem. When I encode the video with Intel QuickSync (from my iGPU (Intel UHD Graphics 730 on an i5-12400), I get upwards of 75% frame loss on my receiving Macbook Pro M2, despite that same system being easily capable of 120FPS display of H264 or HEVC streams. I've played with all the other settings: NVFBC, framerate caps, bandwidth caps, the works. Anytime I turn on Intel QuickSync: 75% frame loss. The second I turn it off: 0.2% frame loss. I tested it on my work mac as well (Also an M2 Pro), and the same thing happens. This is all at 1080p, no crazy 4k stuff here. I suspect this might be out of your hands, and might be a problem with the Metal decoder itself, but I wanted to at least make you aware of the issue.

Here's what shows up in the console when I toggle IntelQuickSync on in the settings while streaming:

Those same 4 lines repeat forever, as long as I'm on QuickSync, and immediately stop when I turn it off. Hope this helps :)

Steam Link macOS 1.3.6.253 couldn't connect with Steam Deck on SteamOS 3.5.7 via Steam version 1700676668.
I'm streaming my gameplay using Steam Link. I'm in trouble.
