In the log i found this:
"10433.364:0028:01c7:fixme:quartz:MPEGSplitter_query_accept MPEG-1 system streams not yet supported"

So looks like another Quartz game to the list #1464, Codecs are MPEG-PS, MPEG-1 Audio+Video

Reproduction

Just launch the game

This issue should probably be renamed "Melty Blood Actress Again Current Code (411370)" to avoid confusion (for reference see https://en.wikipedia.org/wiki/Melty_Blood)

Melty Blood Actress Again Current Code (MBAACC) works with an older proton. I had to go to properties > general > force the use of a specific Steam Play compatibility tool.

Proton 4.11-13 works. I used the nouveau graphics driver on a GTX 770 with reclocking.

With Proton 5.0-9 MBAACC closes while starting.

Hello @namtsui, looks like this is a DirectX 9 game and D3D9 support was integrated into DXVK to translate it into Vulkan. DXVK/D3D9 was enabled by default in Proton 5.0.

Nouveau does not support Vulkan at all, which is why the game failed to run on your system.

You could try adding PROTON_USE_WINED3D=1 %command% to the game's launch options to tell Proton to use wine's DirectX to OpenGL render path, but this is expected to come with a significant performance penalty and is not considered supported.

@kisak-valve Thank you for the explanation.

PROTON_USE_WINED3D allows Proton 5.09 to work with MBAACC. I observe the same performance with Proton 4.11-3 with a consistent 60 FPS with occasional dips during the loading screens.

To get controllers to work I followed this. I successfully tested with an xbox 360 controller and xbox 360 madcatz TE stick.
