We were missing this, and as a result entities list got filled up within
a few frames, which resulted in:
- too many draw calls per frame, same entities were drawn many times
over
- missing entities: if an entity didn't get to that list within a few
first frames, then it wouldn't be rendered ever
This extension allows adding labels to vulkan objects and insert string
labels into command buffers. This is visible in tools like RenderDoc and
helps with debugging a lot.
When running with -vkdebug:
- mark all texture VkImages and VkImageViews with corresponding names
- label brush model draw calls accordingly
1. Improve performance by coalescing multiple surfaces/draw calls with
the same textures (within a single brush model).
2. Add lightmaps. We don't support lightstyles yet, though, so they seem
a bit wrong at times. Also gamma handling is not great.
Oh well.
it's now *very slow* because every surface (which is just a few polys)
gets its own draw call and descriptor bind. F
we also had to make default sampler repeating, so now 2d textures in
menu have weird edge artifacts. also F
making progress i guess
