I’m using it with an Apple Vision Pro with the M5 chip. Version 1.9 is a big improvement - it’s finally possible to adjust the image axis.
However, most SLR Originals videos, as well as many high-quality videos such as VRSpy, do not play at all. I only get audio with no picture. The same issue occurs when using the service in Safari.
My internet connection is 8 Gbit/s, one of the fastest available, so the problem is definitely not related to connection speed.
