Game crash on the first video on 1440p

[Hakushaku]

tl;dr: lower game resolution to 1080p

Running the game on Linux with GE-Proton7-41 and the first video kept crashing roughly after half a second. The error message didn't make much sense:

Context: Get video transform output sample count
Error details: Attribut nicht gefunden.

(Attribute not found)

I tried all kind of stuff with no success, but then looked a few lines below and saw a few lines with resolutions in them, which didn't match my resolution and seemed unusually large for a game video (3840x2160).
I tried lowering the game resolution from 1440p to 1080p and it suddenly decided to work.

Yeah the game is really spazzy for me fullscreen on this display, I was wondering if anyone else was having problems too. At least mine booted! Though, I'm not playing on Linux/Proton, just a Windows 10 setup.

Same issue with Proton Experimental, a 1440p/144Hz main display, and Nvidia 525.53 drivers. Current solution (only tested for a short time) is to run at 1080p windowed until the devs fix their ♥♥♥♥ and export the game properly.

The video files might actually be 4K - I haven't dug into the game's asset archives, but at the very least, opening resources.resource in VLC plays back a 9-second, 30FPS, H.264 video file with a resolution of 3840x2160, although I don't know if this particular file is actually used in-game or if all the other videos are held to the same standard.

For some baffling reason, the PC build of the game is built for 32-bit Windows. I have absolutely no idea how this came to be, beyond general ignorance; neither the PS4 or PS5 support 32-bit applications, Microsoft themselves discontinued new 32-bit builds of Windows over two years ago, and anyone with the minimum recommended 8GB of RAM is also running 64-bit Windows (or at least, I strongly hope they are).

At 1440p with Proton Experimental, I only get 2-4 seconds of choppy cutscene playback before the game crashes. with Proton logs showing failed memory allocation. Trying to force large-address awareness (which I had assumed was still the default on Proton) causes the game to fail to launch entirely, as gmem tries and fails to allocate larger chunks of memory at startup. I'm hoping the game is doing a good job freeing up memory during play, or at least handling its existing memory pool well, and that I'm not going to run into the same issues just by playing longer at lower resolutions.

I suspect this boils down to differences in memory allocation and video playback solutions between actual Windows and Proton/Linux; I doubt this issue actually occurs on Windows or it would've been noticed by now. Regardless, 32-bit binaries and operations that require large memory allocations (like UHD video decoding) are really not a good mix.

As of the 12/21 update, it seems that the game now ships as a 64-bit application. Video playback at 1440p seems to work as expected, at least with Proton Experimental. Unsure if the same is true at 4K or on various other versions of Proton, but I'd be curious to know if anyone's still having this issue after the latest update.
