Linux Discussion

[R3animate]

Hi folks,

In an effort to consolidate some information for Linux users I thought I'd put together a sort of megathread for running IL-2 Korea on Linux for those of us that are keen to try and get it working.

Couple of quick bullet points:

1. This is not a Linux title / the IL-2 devs likely cannot fix these issues for us -- most of the issues stem from 3rd party Linux tools missing features or not having implemented features we need for IL-2 Korea. The game is unsupported on linux and if we can get it running that's just a bonus. 

2. Currently, while you can get the game running; it's not particularly playable - there are some pretty heavy glitches (likely VK3D/Proton related) and a few missing Wine features to work around. 

3. The Linux is pretty solid sometimes and we may get lucky when the Steam launch hits, with enough useful bug reports (with logs) the right people might be able to step in and help get things running smoothly for us -- many other custom-engine titles recently run really well under Proton.

 

With that out of the way, here are the current issues we're seeing and some resources to track accordingly. I am not a Linux guru, I'm just a user, so if you see bad information here, please correct it or let me know and I'll clean up the list. 

 

Issues / Workarounds

1. GetNumaNodeProcessorMaskEx() Crash on launch - This is a Wine limitation; and you can add this to your launch parameters to fix it - "OMP_NUM_THREADS=% KMP_AFFINITY=disabled %command%" (set % to your threadcount).

2. Hanging logins - This doesn't seem to be effecting everyone, I'm not impacted and at least one other person on the github issues page said they weren't either and logged in normally.

3. Shadows glitching in menu - known / suspected VK3D / mesa or proton thing.

4. Ground textures not loading correctly - known / suspected VK3D / mesa or proton thing. 

 

Resources / Links

Current Linux install guide is attached (will be updated as time goes on / new workarounds are discovered)

Proton Github Issues page for IL-2 Korea - https://github.com/ValveSoftware/Proton/issues/9906 . If you can, follow the templates and provide logs if you see a new issue. It will help developers dig into the root cause and fix accordingly. It will also help other keeners nail down which component has issues. 

vk3d-proton github issue for the texture issue only : https://github.com/HansKristian-Work/vkd3d-proton/issues/3134

ProtonDB for IL-2 Korea won't go live until August 4th as the site relies on showing data from verified game owners.
