I picked your first point just to have a laugh, sooooooo (my sleeves are very long to roll)
I actually have 620 racing cars and here is my...
"Triangles Hall Of Fame":
851k rss hyperion
825k rss protech
788k rss furiano
764k Ferrari F40 LM
The one that makes laugh more is the VRC isola/isotta fraschini, in order to use that futureless disgrace of an amateur proto our pcs have to move 710k triangles around the track.
Another funnyfun paradigm is the the rss protech uses almost twice the number of triangles than urd darche992 23.
Is it twice as good? Naaaaaaaaah.
But in the end I don't even have a SINGLE four-figure k triangles model.
And by checking all the payware mods everybody can clearly see that RSS, and lately VRC too, have stopped caring about optimization.
The very good looking ripped Valkyrie appearing on these very pages is a 345k tris model, almost half of the mentioned brands.
p.s.
My point wasn't really try to nuke your point...but it just happened

This plus the fact alone that my AC doesn't wanna race anyway.
The good thing about the 4000k tris models is that they are out so hopefully someone in the future can reduce that frightening number.
Also, in terms of sheer performance: doesn't really care if a model has 300k or 700k triangles because the CSP stuff is making even the lowest triangles model super-heavy.
