This is a big one:
- Reworks the discard signal almost entirely. Now has a normalized 0..1 discard signal: distance x size x channel exponent, floored by staleness and background app state. Shaped by VRAM pressure.
- Textures can now scale down to the smallest GPU mip (1×1), independent of the codec's encoded mip
count.
- Terrain texture LOD now works. Useful for 2K textures and PBR on terrain. Based upon camera distance to nearest terrain patch.
- New texture quality setting. Low/Medium/High/Ultra
- Caps texture resolution on Low to 1024, and otherwise shifts the discard signal around. Makes distance based texture LOD work a lot more predictably.
- We now track last bind state for textures, and discard accordingly. We progressively discard based upon last bind time.
- Avatar textures get a residency boost to stay loaded in VRAM longer under pressure.

QA found no difference performance wise, I see a decrease in performance.
