I figured out we no longer have to do software rendering, the Greed Processing Units are capable of doing graphics. So I continued working on my game engine jan-kelemen/niku.

With the exception of toji/optimized-sponza asset, all other assets are from KhronosGroup/glTF-Sample-Assets.

According to the profiling results of the gltfviewer demo, rendering is bottlenecked by the sampling of texture images. I’ve known about this for quite some time already, though I think I can’t do much about it, since the shader cannot invent pixel values out of thin air.
