Hookshot version

2.0.2

What kind of problem

Low fps or stutter

What happened

Hookshot version: v2.0.2 (source 998ef8f9). Also tested a device-lost-fix build (source caaaf2b7).
GPU / driver: AMD Radeon RX 6650 XT, Adrenalin 32.0.21045.16010, Vulkan 1.4
CPU / RAM / OS: Intel Core i5-10400F, 16 GB, Windows 11 Enterprise LTSC 2024
Where: Shader preparation at boot; stutter when entering new areas (e.g. leaving Kokiri Forest towards the valley).
How often: Every time the program cache is empty.

What happened

With an empty program cache, preparing shaders takes a very long time:

Log	Build	Program cache at start	Result
hookshot_log.1.txt	v2.0.2	0 keys	`prepared 31985 shader programs (39842 new, 0 failed, 3808 stage libraries) in 449.8 s`
hookshot_log.2.txt	device-lost-fix	0 keys	`prepared 14179 shader programs (21671 new, 43 failed) in 69.6 s`; ~31 "does not lower" errors
hookshot_log.txt	v2.0.2	39927 keys (~5.6 GB)	no recompile, but `1185 pipelines (1421 ms)` and several frames over 40 ms

I also felt waits of roughly 10 seconds or more when some shaders load. I did not time this precisely, so it may only be the cold start.

Expected

Faster preparation, or at least clear progress/time-left, and fewer hitches when entering new areas once the cache exists.

Notes

I read #617: compiled shaders are tied to GPU and driver, so this cannot be shared. This request is about speeding up or smoothing the local build (e.g. more parallelism, background compile, better ETA).
The 5.6 GB program cache seems large; not sure if that is expected.
The log also shows a 12288x12288 texture upload taking 334.7 ms.
Related visual bugs I commented on: #659, #696, #667.

Logs: hookshot_log.txt, hookshot_log.1.txt, hookshot_log.2.txt (attached below).

Analysis created with Claude; it may contain errors.

Before you send it

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.

#727 should fix the shader lag when entering new areas

Tracked in #995, follow there. That issue collects every report of low FPS while the GPU is not fully used, and shader stutter, and this one is linked from it with its GPU, version and log details. If it still happens on v2.0.6 (https://github.com/NotRexed/Hookshot/releases/tag/v2.0.6; Update next to Play in the launcher), please add a comment there with your hookshot_log.txt.
