Honestly maybe.
Even the normal/upscaling Dlss I find unusable due to smearing/ghosting on any glass instruments. I find it annoying in 2d but in Vr it drives me crazy. So I’m personally not locked in nvidia.
But your probably better off asking directly in the Radeon threads to actual owners. Last I heard vr had some issues on Amd but I don’t want to spread half/outdated knowledge. Also the additional vram may very well offset whatever slight dissadvantages radeons might otherwise have.
