Clearly, this is less optimized than Skyrim or Fallout 4 even in the texture department.File size optimization is a dead art in a lot of modern big games. Expect gigantic data storage for the most mundane of things typically.

Ignore the file sizes, BSA browser seems to not fully work with the new BA2s at the moment. But they are using separate textures for every single channel, including AO. This multiplies the file size by a vast amount when they could be packing a bunch of stuff into single textures. AO could be packed with Roughness (or literally just bake the AO into the colour, all that happens to it in PBR is that it gets multiplied on top anyway, its pointless), normal could be packed with something in the Alpha channel, or even the Blue channel if they solve for Z in shader like they did in Skyrim. Skyrim packs specularity into the normal in the alpha channel, so all objects are just colour and normal, since colour uses alpha for alpha, where as this just uses completely different textures for everything. There is 40gb of texture BA2s and they could cut down each texture set to 4 or fewer textures down from 6 or even 7 with metalness, probably saving upwards of 10+ gig, and lowering the VRAM usage by a lot as well, since you don't need to load 6 or 7 4k textures into memory.
