i tested some games and i do not like Z3D. But in G3D games i have low frames because of my weak pc.
I have heard that vorpx supports AFR in CP77 and the Witcher 3, which is the best compromise to have lower quality G3D but it is playable with my weak PC
Some games have great G3D, are quite amazing in VR and aren’t very demanding. You could try Bioshock 1 Original & Infinite. I played them in 2880p with a GTX1080 (but I had a Reverb G2). Maybe Bioshock 2 original (I already had my RTX4090 so I don’t know).
I guess most DX9 games (except very beautiful ones like Metro 2033 original) should be Ok. Maybe Dishonored 1 (excellent game), probably F.E.A.R 1 (great AI), Dark Messiah (best sword combat and emergent gameplay), Clive Barker’s Jericho (probably very good in VR), etc.
