Does anyone know, to use my PCVR games on the Quest 2, if I have to totally disconnect my Vive and go through another set-up process in SteamVR? I'm seeing tutorials that say I'll see a SteamVR icon in the Oculus App's screen, but maybe that's old info.
You can stream your Steam (or other VR PC) games to the Oculus, thus taking advantage of the superior processing power of the PC. Or you can buy games you download directly into the Oculus if you want a 100% portable experience. For PC use, you can either use a (specialized) USB-C cable to connect them or else you can connect the Oculus to the PC via wifi for a cordless experience.
just to add to that, the quest 2 is better all around than the original vives (and the pros) and the rifts, spec wise. It has a higher resolution and refresh rate than both. It even has a higher resolution that the index, though the index wins out on FOV. The one place the wired sets can generally win out is on tracking, just because they have outside in tracking instead of inside out tracking, since the quest can only guess about things like you moving a hand behind your back
As an OG Vive owner, after using the Quest 2 for a couple weeks now, I'd argue that the LED screen of the Q2 is nowhere near as good as the Vive's OLED, mind you, I did change out the lenses it came with. I can't find any settings in the Oculus menus to make it's blacks not look like washed out grey.
The Index controllers are also much more preferable to the Touch, as the texture/grip/hand loops are the way to go until some sort of (affordable and mainstream) VR gloves with force feedback is available.
If cost is strictly a factor, though, Q2 is obviously the winner, facebook bs notwithstanding.
