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.
Well, I first played Dragon Age Origins with the framerate fluctuating between 10 and 20 FPS. Wasn’t the most fun I’ve ever had, but ever since 30 - 60 felt like luxury. So yeah, anywhere from 10 to 30 is fine for me, but the more active a game is the closer to 30 minimum with a target of 60
