Description

Game Name?

Any game (Wii or GC) choosen.

What's the problem? Describe what went wrong.

On macOS choose "Vulkan Backend" an enable "GPU Texture Decoding" (Safe or Fast).

Start a game:
- With a GC-game the N-Logo is displayed but will crash immediately when the intro screen of the game appears.
- With a Wii-game it crashes immediately, no Wii logo is displayed.

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

Dolphin dev version 5.0-10772, tried also older dev-version, but same crash, it seems to be an issue in the function Vulkan::CommandBufferManager::SubmitCommandBuffer()

Is the issue present in the latest stable version?

No since stable version 5.0 is 3 years ago and no Vulkan Backend for Dolphin existed then...
However with OpenGL backend it doesn't crash when "GPU Texture Decoding" is enabled.

Tried recording with Fifolog, but here it's clearly not a graphical issue...

Crash with:

Application Specific Information:
-[MTLIOAccelComputeCommandEncoder bindEmulationArguments]:53: failed assertion `No compute pipeline state bound'

#1 Updated by JMC4789 19 days ago

I mean, probably the best we can do is just disable the option. Apple is not making it easy to support their OS.

If you want a far better experience, literally use any other supported OS than macOS.

#2 Updated by gilcel 19 days ago

Ok thanks ;-)

However Vulkan runs much better, even faster than OpenGL on macOS...it's only this issue (hopefully someone will find a solution).

#3 Updated by Pizuz 17 days ago

I get a segfault instead, however I'm on nVidia. Wind Waker manages to show the Nintendo logo and the Dolby ProLogic II logo before crashing.

This seems to be a regression in Dolphin, because 5.0-9431, which I still have lying somewhere, doesn't crash with GPU Texture decoding enabled. Current master crashes with any MoltenVK version I tried (1.0.26 released earlier than that).

However, I observed that starting with MoltenVK 1.0.35 (the one currently bundled with Dolphin) GPU Texture decoding stops garbling textures, so this might be worth investigating further.

#4 Updated by Pizuz 17 days ago

To specify further: The regression must have been introduced somewhere between 9431 and 9694.

#5 Updated by JMC4789 17 days ago

Feel free to find the exact build, so I can tag whoever caused the regression. That'd help a lot :)

#6 Updated by Pizuz 17 days ago

Found it.

5.0-9638 (Move a significant amount of video backend logic to VideoCommon - PR #7753 from stenzek) is the first version that broke it.

I guess this slipped by, because no one would use GPU texture decoding on macOS anyway with all the garbled textures it produced (until 1.0.35 apparently).
