The current performance requirements have been around for years and pc specs have greatly improved since then, it's also a bit inconsistent with 1 single triangle over the 70k recommended being "very poor" and the texture memory being just slightly higher being just "poor" and excellent avatars have game breaking shaders that tank peoples framerates more than a avatar with 70,001 triangles.

With performance gated instances being implemented I feel the performance ranking system needs a overhaul as having instances only accept "good" performance means that everyone has to decimate their avatars like crazy to conform to a standard in a instance. As far as how to overhaul the performance ranking is beyond me I barely even know how to add a different texture to my avatar but I'm sure there is some way to make the system itself more optimized and not so strict on creators.
