Giving feedback here as requested in https://feedback.vrchat.com/feature-requests/p/add-vram-to-in-game-avatar-performance-view .

Current "texture memory" section, as you are well aware, does not include the VRAM taken by meshes.

I believe it would be to everyone's benefit, if you added mesh VRAM use there as well.

According to Thry's Avatar VRAM Calculator, one of the most popular avatar bases in VRChat (at least among furries), Rexouium, in its base form, uses around 115MB of VRAM. A not insignificant portion of that is the mesh, taking 53MB by itself (46%). Also while it's pretty easy to lower texture resolution, and therefore that part of VRAM usage, simplifying the mesh to achieve the same effect is way over many people's heads.

My own main avatar, after some optimizations to both textures and mesh uses around 58MB of VRAM, out of which 39MB (67%) are the meshes.

Clearly, the mesh sizes aren't insignificant.

Showing only the texture sizes ignores a part of the problem and make it seem that some things are much better than they are in reality.

Mesh VRAM usage could be added either as a separate position or you could just sum them up. Doesn't matter that much.

However, when you add it as a metric of the avatar performance rank, it would make more sense for it to be summed up.
