Yes. Apple Vision Pro has its own browser, and that is all it takes: Hrava runs the game on your Mac and streams the picture to the headset over Wi-Fi. Nothing needs to be installed on Apple Vision Pro.
Vision Pro gives the sharpest picture of the lot: micro-OLED renders a 1080p stream almost like the Mac display itself, and the Safari window can be pinned in space and resized to taste. Safari for visionOS supports WebCodecs, so hardware decoding works. Control it with the Mac keyboard and mouse or a gamepad; no controllers ship in the box.
Display: 3660x3200 per eye (micro-OLED) · Browser: Safari for visionOS

No. It is a big virtual screen: the game stays flat, like on a monitor. There is no stereoscopy and no in-game head tracking.
A normal 5 GHz home network is enough. If the picture stutters, switch Hrava to 720p60 or 1080p30.
Install Hrava, turn on VR streaming - and see for yourself in minutes.
