As of right now, it is very unfortunate that we are seeing increasing amounts of avatars that are both popular but also are made in not the best interests in regards to performance.
Myself I always attempt to make sure whatever I make is not a big offender while still trying to keep up with things. I know how to make a Good rated model but have unfortunately ended up realizing that the current set of limitations we have are not quite as fairly adjusted for the creators.
For someone starting out as a creator, the performance limit sheet could very much be treated as a ladder for anyone to climb and get better, but sadly the limits for Triangles/Polygons is not doing this any favors.
It has become what is for many people, a brick wall that shuts the door on any newcomer and instantly labels it as a Very Poor creation despite the fact that in many cases where some beautifully created models that slightly dance over 70k gets treated exactly the same as a model with 700k which is really sad to see. Cause 71k is really not the same performance impact as 700k.
And at this point I see it more and more often that people are just simply giving up on this alltogether and creates "monstrosities" cause why bother when its all gonna be labeled as Very Poor anyway?
I think this is a very big downside and I would really hope we could instead get a change for limits to Medium and Poor to make them viable options for creators to reach for.
If Medium and Poor are realistic options for creators, we will without a doubt see an increase in usage for these ranks by the creators as they would in many cases try to avoid Very Poor rating and over time stretch to both Medium and in some cases also Good rating.
This would in turn over time have a positive effect on VRChat as a whole as the standards would be shifted towards more performant avatars with admittedly less "bloat" and a more sustainable gameplay experience for a lot of users as people would gravitate to avatars with better performance ranking than Very Poor who appears to be the standard today.
A tradeoff could even be limiting the texture memory limits as todays limits are pretty generous and I think we would still see people get by without issues.
Implementing these changes would also not negatively affect previous creations and in some cases would give some unfairly ranked creations better ranking than before, leading to a happier playerbase that would also be more capable of telling "is this avatar good or not?" compared to today where it is quite dubious and obscure information on this topic floating around.
There are a lot of nuances to it all but I believe for inclusivity and positive long term goals I think giving Medium and Poor a better spotlight than it has today would be a very big gain for a lot of the community.
I would be really excited if you gave this some thought cause I love VRChat and would hope to see it go well in the future too, and this would be a really big stepping stone in a good direction.
