For me, anything 25 FPS or higher is 100% fine and I’ll be enjoying my time. I never play competitive online shooter games ever, though. All single player ones like GOW and the likes. I game on a 60 Hz 4k monitor. GPU is AMD RX 6600 alongside Ryzen 7 5700G and 32GB RAM. My games are set to meduim most of the time at 4k. Demanding titles are on low. Surprisingly, GOW and GOW Ragnarok are both set to ultra and I still get around 40ish FPS.
Weirdly enough, I actually care more about framerate on “pancake” (non-vr) games than I do on VR games. I can deal with 10fps in vrchat in a crowded instance. I need more like 20~30 for non-vr games.
That said, I get mentally exhausted when the framerate is <30 for an extended period of time in VRChat.
I can’t do VR. It scares the shit out of me having a screen 2" away from my eyes.
