I tried my quest 2 on my PC with a GTX970, works but not as smooth as my laptop with a 1070. So on the PC I use a webcam with viewtracker and I use the Quest 2 on the laptop. Can't wait til I can upgrade the video card
I run everything on low with a couple of exceptions. Textures on High, resolution at 1080 ( only makes a difference on your monitor not VR), shadows on low flat, trees at about 40% and map preload maxed (should have an ssd or better yet nvme m.2) and still have pixel density at 1.0
