hi,
it depends on the game ! On HMDs with ultrawide fov, resolutions with 21:9 or 16:9 makes sense, but on the G2 with its small fov i would prefer 4:3 or 1:1 Resolutions. But it depends if you are playing in FullVR or CinemaMode, too. In CinemaMode without highest zoom, i would prefer 16:10 ! For High-End Nvidia or AMD cards i use resolutions like 2880×2160, 2560×1920 or 2160×1620 in games with G3D. In games with Z3D i use resolutions like 4000×3000, 3600×2700 or 3200×2400. With my RTX 3080 i have to set medium or sometimes high graphic details, it depends on your graphic card. In my opinion the resolution is much more important than the graphic details !
