Hookshot version

v2.0.11

What kind of problem

Crash, freeze or black screen

What happened

Hookshot v2.0.11, Steam Deck (RADV VANGOGH).

Note: the log names the app mkw-recomp, but this is Ocarina of Time.

The game reliably hangs the GPU near the Deku Tree, especially when looking around. The kernel shows ring gfx_0.0.0 timeout … Process hookshot followed by a GPU reset.

There’s also heavy flickering, with or without the workaround. The logs show repeated “upload over a drawn image” on screen-sized targets (1536×864, 384×216).

Where in the game

3D rendered areas, only Kokiri forest so far

How often

Every time

Graphics card and driver version

RDNA 2

CPU, RAM and operating system

Van Gogh, SteamOS

Changes from the defaults

Workaround (Thank you claude):

RX_VK_SKIP_CODE=463f42630fce83a0,d38b0d52a94ab5a8,40d0c0768e874600

RX_VK_NO_EXTREGS=1
also avoids the hang, but ~20 shaders then fail to lower and ~87 draws per frame are dropped.

Other software hooked into the game

No, nothing hooked in

hookshot_log.txt

RX_VK_CHECKPOINTS=1 identified the hung draws:

mesh program 89ca750f9852b7ca = mesh 1c45a2b32040620d + pixel d38b0d52a94ab5a8
mesh program 636eed4d5000d1c0 = mesh 0801cca176fd6c81 + pixel 40d0c0768e874600

Both pixel shaders are “lowered with extended registers”. 463f42630fce83a0 (also extended-register, used with a mesh shader) caused earlier freezes too.

Screenshots or video

No response

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.

Thanks for the detailed report (ring timeout near the Deku Tree, mesh draws with extended-register pixel shaders, uploads over screen-sized drawn images). Steam Deck GPU hangs are tracked in #1000, which links this. Closing this as a duplicate; please follow #1000.

Also-- is there any way to get my save files from Lichii over to Hookshot? Idk much abt how the save files work I havent poked around but I imagine it is hard if not impossible..
