It's undeniable to say that what's made vrchat so popular is its own playerbase. The ability to freely create any worlds or avatars that you wan't is something that very few VR games offer.
There's a very thin line between creativity and performance. While I'm sure that previous patches have hurt some people I'd argue that they were necessary for creators to optimize their stuff.
But this update has just completely obliterated that line in favor of performance. Yes, you could argue that you can still upload poor/very poor avatars but let's be honest here we all know most people are gonna block them by default. VRChat has just lost one of the fundamental aspects of what made it so great. Creativity
If an user is "clever" enough to somewhat make use of animations for props, particles, etc surely they'll care enough about the game as to keep it optimized( example: a flashlight that they only pop up in very dark maps or a snail marker that only pops up when drawing). And if not, well, anyone can always block them manually.
I've been playing vrchat for more than a year now and let me tell you that this is a HUGE mistake. Please revert this change. You're killing the game
