Hookshot version

v2.0.11

What kind of problem

Low fps or stutter

What happened

Since updating from v2.0.6, gameplay runs at a steady 11-15 fps (Death
Mountain Trail, Kakariko Village, and the pause menu). The title screen and
loading screens still run at 60. On v2.0.6 the same areas ran at 40-60 fps.

In the logs, the GPU itself is the slow part: "GPU time" is 60-100 ms a frame
in play on v2.0.11, against 6-12 ms on v2.0.6. The "memory sync" in slow
submits (30-70 ms) is the main thread waiting on that GPU work.

Things I tried, each made no difference:

RX_VK_WB_DIFF=0 (log B: the write-back diff off, still ~11 fps, GPU time ~77 ms)
RX_VK_ASTC_RGBA8=1 (log C: big ASTC textures as RGBA8, still ~15 fps, GPU time ~61 ms)

Attached:

A_v2.0.11_default.txt: v2.0.11, no switches
B_v2.0.11_WB_DIFF_0.txt: v2.0.11, RX_VK_WB_DIFF=0
C_v2.0.11_ASTC_RGBA8.txt: v2.0.11, RX_VK_ASTC_RGBA8=1
D_v2.0.6_for_comparison.txt: v2.0.6, same card, normal fps (this run ends in
the separate Kakariko -> Death Mountain Trail crash I'm reporting on its own)

Possibly related, from the v2.0.7-v2.0.11 changes: 04675cf (BC images get
STORAGE on AMD, so the game's BC encoders now run there) and the AMD BC
encoder PR #1052.

I'm on the newest release, or the problem is still there on it.
I searched the open issues for this problem.
I'm not attaching game files, keys, hookshot.exe, the .bin caches or saves.

Thanks for the careful A/B logs (v2.0.11 GPU time 60-100 ms a frame against 6-12 ms on v2.0.6, unchanged by RX_VK_WB_DIFF=0 or RX_VK_ASTC_RGBA8=1). Linking this to the FPS tracker #995 and AMD rendering #1006; the BC-encoder lead (04675cf / #1052) is a good one to check.

Thanks for the report. Reports of the same problem are now collected in #995, which lists this one with your details and links back here, so one fix closes them together and the open list stays readable. Follow #995 for the fix, and add new details there (or here). If this turns out to be a separate problem it will be reopened.
