Model Data + Near Plane & Detail Culling Dithering + Zone Reveal Fade + Wind & Character Displacement

[RuffledPlume]

Uses ordered dithering to fade out geometry that is about to clip with the near plane

The code looks good to me, but I think we should add a toggle for this, which removes the extra fragment input when disabled, so this performance difference is an opt-in thing:

Rebased off master & added detail model culling:

Ready for review, the dither options is behind a config so can be opted out to reduce performance cost:

Wind & Character Displacement:

ZoneRenderer.Displacement.mp4

Adds FrameTimer Graphs:

This was moved to PR: #1139

@aHooder I've optimized the Dithering such that only Zones which intersect with the camera with a radius of 2 tiles draw with discard variant of the scene shader. Here a before & after:

Before:

After:

So I think it should be safe for this to be enabled by default?

I think we should keep some explanation of the format, since the layout no longer matches the vao binding layout

Removal of this check helps IGPU, since the staging buffer is meant to help coalcse the draws into a single drawCall

The offsets & byte counts were kinda nice, but the (24 bytes) thing is already in a constant directly below it, and I'm not sure how useful the (unaligned) thing is. The main reason I figured it was LLM is because it removed the info about how two flags are packed into the textureFaceIdx, which imo really should remain specified somewhere.

Stale & mentioned issues have been resolved. The remaining issue at this point is the GPU performance, even with dithering disabled, but the PR is still a big win on the CPU-side & bringing feature parity with legacy, so this is arguably good to go.
