At 30 fps, I expect the court and active player models to look pretty similar to the PS4 overall. Crowds were always going to take a massive hit.
Sonic Forces looks shockingly close to the PS4 version just at half the framerate, so I hope that's the case here. I prefer higher framerates, but it's really just up to the dev team's priorities.
Would be nice if they were able to give us a choice ala FE:W (though it's nothing short of a miracle we're getting that option there on a console).
The screenshot making the rounds looks pretty bad, but impressions are positive so maybe it's just an unflattering crop.
