I have only just begun the game. The first part of the game plays well on a Steam Deck, but I cannot speak for the rest.

Yea, this crash is annoying. I spent a long while trying to get this working a few years ago and failed. It's caused by a shader function this game uses not being implemented fully into wine, since in all other known cases the function just returning "true" worked fine.

There are two ways of fixing it:

1 - You use the Wine Patch made by Paul Gofman that reimplements some of these shader functions, however it is outdated and a pain to use and is therefore not really a good option.

2 - Since these shader functions are only used once before being cache, if you had the cache files from a completed windows playthrough of the game, you could move them into the appropriate folder within your game's files and it would no longer need to use the shader function, bypassing the crash.

So basically until someone puts cache files online or the patch is refined and mainlined, there isn't much we can do. Here's the bug report (comtaining the deprecated patch) if you are interested: https://bugs.winehq.org/show_bug.cgi?id=47229

I might do a playthrough of the game on a windows drive and put the cache files up, but it's a lot of a hassle to do for someone who daily drives linux.

UPDATE: I've setup a windows install on a 200GB partition on my second drive and am gonna replay through the game, I'll put up the required cache files when I've finished alongside instructions on how to install them. I'll add another message to this thread and a ProtonDB entry when I've finished.

That is very, very much appreciated. I was considering just ignoring the game until it was (hypothetically, eventually) patched.

That is an incredible amount of effort, thank you!

Just for my information, is this still the plan, and slowly progressing, or did you decide to not do it?

Again, not a complaint or a push, but just so I know if the Windows playthrough to get the cache files is still intended.

Curious on progress here.

Same, any word?

Did you ever end up doing this?
