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.
I know OP has a point that they weren’t asking your opinion on games, but I really like your stance of demanding performance from the game devs especially on older hardware. There is a culture of "must have newest hardware to run everything maxed " that’s just dumb consumerism.
