This game is actually very very smooth. The developers really optimized VRChat for Android so well. It also has so many worlds to explore. The graphics are alright not too bad, but not too good either. Honestly, who cares about graphics? I'm not going to criticize it for that; it's decent for an Android game.
However, the main problem is the players. They are cringe, disgusting, and there are so many bad things about them. Let me tell you something: when you join a world, there's a 90% chance you'll find some 6-11 year-old kids with a naked avatar of a fat man. They'll speak loudly with their broken-ass microphones, constantly saying cringe stuff. If you've played the game, you know exactly what I mean. If you hate edgy behavior, this game is DEFINITELY not for you.
