There's a whole thread on that.Quest 2 arrives tomorrow
Virtual desktop, apart from buying it is there any sort of setup I need to do?

I left it on defaults pretty much, and it seemed to work fine. Until I noticed the latency. Waiving hand around it quickly went out of sync with my movements. But it wasn't initially noticeable, but the whole time I used VD I felt off, slightly sick. I decided that I was much more comfortable with the cable. That said, if you have a Wifi6 setup you'll have a better experience than I had. You need to install a VD streaming client (available from their website).
Honestly, if it's not a native quest app, I rarely play it these days. I suppose partly because the PC is really my sons, and partly because I can't be bothered. Native Quest apps are so convenient. Steam VR can be hit or miss to get running.
