Rendering
City scenery now draws with 273 draw calls instead of 1,752 (around 6-7x fewer). Trees, walls, and props are instanced now instead of drawn one at a time.
Memory
Put in a draw distance so distant map parts stop rendering when you can't see them.
Quality Settings
Fixed the quality presets that control shadows, lighting, draw distance and resolution. Included dynamic resolution to help weaker rigs hold a framerate.
Textures & Cleanup
Mipmaps turned on to fix distance shimmer and save VRAM. Cleared out around 144 unused assets left over from the old conversion.
Under the Hood
Stripped dead ray-tracing shaders and turned off a global illumination system that wasn't actually doing anything.
