Depends on what you’re used to, I guess. There are millions of Fortnite players on the PS4, and many of them would kick our butts even on 30fps.
I like my stable 60+ fps of course, because it’s more eye-friendly. But 30 fps don’t feel too bad either. I mean, real 30 fps, displayed on an fps counter, not some “it’s choppy, must be 30 fps” guesswork benchmark.
