Update of my Ancient Egypt Project

Ah, the famous Egypt scene that we got a video for

I see there is some room for further optimization with regard to texture size. Some of the textures are non-power-of-two (not 512, 1024 etc) which causes the engine to re-scale them during loading. E.g. Map #4627 – 1018×800 (see the performance profile)
There is also a map texture with 5kx5k size which can probably be down-scaled to 4096×4096 px.

Real-time shadows is a real bottleneck in this scene – I dunno if those can be baked. Or may be cascaded shadows can be enabled instead of the single 4k shadow map.

I wonder if the shader optimizations we introduced in Verge3D 4.8 pre1 would help to increase the FPS?
