Getting VR legs is tough. I can't play anything with typical locomotion for more than 20-30 minutes before I want to hurl. However, good vision tunneling helps a lot. VRchat gives a vignette and a stationary grid while you're moving if you have tunneling on and even at low tunneling, I almost never get queasy while running around or even flying or using grappling hooks. It does sucks how few games actually have this option though, and even fewer that do it well enough that it makes a difference (just having the vignette doesn't really help; but having the grid lines that don't move sure as hell does).

I'm using a Quest though; there are a lot of games on the HMD or on PCVR that either are played while sitting and you never move anywhere other than turning in your seat, or room scale games where you just walk around a 5ftx5ft square so you can actually walk for real and not get the inner ear weirdness. Like Beat Saber or I Expect You To Die. I favor those more than, like, Skyrim VR or other flat space games with VR mods or additions.
