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.
In this day and age, anything below 60FPS 1080p is unacceptable. If a new game can’t hit that target on 3 year old hardware, the game is unfinished.
I’m asking YOU and what YOU think is playable and you’d enjoy it , not games.
I think 60FPS is totally fine. 30 is only OK on slower moving games or era-appropriate consoles; Halo on the OG Xbox for example.
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.
