You’ll need Oculus Software for starters.
Some will say you need the Oculus Tray Tool, OpenXR Developer Tools and/or Virtual Desktop depending if you want to go down the rabbit hole that is wireless!
I’ve found that with the right drivers and careful optimisation I don’t actually need the tray tool or OpenXR as it runs fine out the box and I don’t notice any difference at all. And I have experimented a lot.
On Nvidia at the time of writing, a clean installation of 457.30 drivers gives the best performance.
You’ve no doubt seen CptLucky’s fantastic guide on this forum. It’s useful for Quest2 as well because there are many cross-over principles to follow.
