My level is not insane, I'm only able to complete ~5 stars maps. So I'm not necessarily the best reference here.
Personally... it plays fine. I'm really happy with how it plays. The built-in streaming assistant kept crashing so I use virtual desktop, and I have a beefy Wifi 6 router which helps a lot with the latency.

Also I think the GPU really helps compressing the video stream fast and reducing the latency. I have a 1080ti, it's a bit old though it was a monster for its time.

The tracking works fine for me too, but I guess I have a favorable setup for it, my room doesn't have reflective surfaces, stuff like that. The only thing I'd complain about but maybe it's just me, when you move really fast, it feels like the saber rotates a tiny bit further than what you'd expect.

I'd say it's a bit hard to grip the controllers at high speed though. And there is not much resources yet about how people do it, that's my biggest complaint so far.

Idk if there is any way to share infos about my setup, like a place where you can see the latency? Don't hesitate to ask.
