Hi! Following up on #2058 (closed and merged into #993).

Setup: RX 6750 XT (RDNA2), Ryzen 5 3600, 16 GB RAM, v2.1.0 with RX_VK_COMPACT=1, 1080p output, cap 90.

VRAM is fixed with compaction, thanks. What's still left on AMD:

Low FPS: Hyrule Field 24–40, Castle Town 16–22. Per frame ~37 ms of CPU replay/submit (draw 23 ms, descriptors 10 ms) + ~22 ms GPU, with ~3000 draws. The same game runs well on an RTX 4060, so it looks like the AMD path needs optimization (task/mesh shaders on the compute fallback, 11 programs "not translated: a network left out on this card").
A 41 s stall when entering an area: working set dropped from 11.9 GB to 5.9 GB (private ~29.9 GB on 16 GB RAM), which looks like paging.

Is there a plan or timeline to fix these on AMD? If not, I'm thinking of forking Hookshot and trying to fix the AMD path myself. Any pointers on where to start would be appreciated.
