Optimize renderer #35

Closed w23 closed 6 years ago

w23 commented 7 years ago

The entire Half-Life 2 mesh is like 5fps on AMD Radeon FURY X. This is unacceptable.

Things to try in no particular order:

[ ] map frustum culling
[ ] face frustum culling
[ ] bsp node frustum or pvs culling
[ ] dynamic per-material batching of visible faces
[x] pre-sort vertices by material for VBO offset 64k splitting
[ ] one giant VBO for the entire mesh
[x] skip material and lightmap textures for distant maps, do baked color instead
[ ] combine most popular regular material textures into atlases to avoid splitting draw calls

https://github.com/w23/OpenSource/commit/91d54c4cbac04701fb9d70cd3851624e60016b94 improves rendering by discarding materials from far levels. Need to compute average material color to fix level popping.
