If you give it some time, it should uncompress the textures and compile shaders. It takes a while, but its worth it, even if just from a technical stand point to see how they created the assets. It’s not as much as an issue for an actual packaged game, since the shaders will already be compiled. You’ll still need to work within your VRAM budget, but so far, after the initial load, the assets are fine.
