The same for me on 3.7 and 3.7-4 beta

Hello @adrianlshaw, is this a recent regression for you? Please check if PROTON_USE_WINED3D=1 %command% has an effect.

Separately, please check if PROTON_FORCE_LARGE_ADDRESS_AWARE=1 %command% has an effect.

Hi @kisak-valve thanks for the swift response.

Adding PROTON_USE_WINED3D=1 fixes it.

Separately, adding PROTON_FORCE_LARGE_ADDRESS_AWARE=1 also seems to work.

I don't know with certaintiy if it's a regression, however I just reverted to 4.11-12 and it works perfectly without any launch options.

Kkisak-valve maintainer 2020-02-18 github

Thanks for checking, Proton 5.0 enabled DXVK/D3D9 by default, and it's using more resources than before. You'll want to use PROTON_FORCE_LARGE_ADDRESS_AWARE=1 for this game going forward because the WINED3D render path is expected to come with a performance penalty.

As requested by @kisak-valve, I am reposting my feedback in this thread.

The game crashes whenever you alt-tab to another running application if you are running the game in fullscreen mode. The game will not crash if you are running it in windowed mode. I have used both Proton 5.0-5 and 4.11-13.

Here is my system details, and here is the logfile. To generate the logfile, I first cleared whatever logfile is present for the game and then started the game in fullscreen mode. Once I reached the main menu, I alt-tab to another window.

Wasn't sure whether to make a new issue or not so apologies if this is the wrong thread.

In the latest version of Proton and GE the game will close without an error after approximately 10-20 minutes.

Ubuntu 22.04.1
Occurs on Proton 7.0-5 & GE-Proton7-42

Have tried PROTON_FORCE_LARGE_ADDRESS_AWARE=1

I've attached a log below

steam-24790.log

The game worked fine previously, not sure if this is a system issue on my end or with the game.

Kkisak-valve maintainer 2022-12-08 github

Hello @Jackson-Bondy, what's the newest Proton version you know wasn't affected by that behavior? Also, please copy your system information from Steam (Steam -> Help -> System Information) and put it in a gist, then include a link to the gist in this issue report.

As a side note, PROTON_FORCE_LARGE_ADDRESS_AWARE got enabled by default for all games run with Proton a fair while ago, so manually setting that on will have no effect these days.

JJackson-Bondy 2022-12-08 github

Hello,

I'm not sure on the previous version that was unaffected but I have just tried an hour or two on 3.7-8 without any crashes.

Proton 3.7 is from 4 years ago. That's an unreasonable amount of time to ponder your issue as a regression.

JJackson-Bondy 2022-12-09 github

I've gone back through every version as far as 5.0-10 which still has the same issue, different log now however which I've attached.

I am almost certain I have played the game in 2021 so I can only think this must be some sort of kernel/Ubuntu update which is causing an incompatibility in newer versions of Proton.

If I get time I will keep working through previous versions until I find one which is working fine.

The end of the logfile is:

X connection to :0 broken (explicit kill or server shutdown).

Just picked this up today, seems to work just as I remember it on Windows, running on Proton 8.0-2. Only issue I had was switching windows (Alt-Tab) results in a blank screen when returning to the game.

WWedge009 2026-01-25 github

The aforementioned issue was resolved recently - I think with the release of Proton 10.

I don't normally play across different computers but I noticed an issue with file synchronisation similar to what I reported for Kane's Wrath, even though there's no complication with apostrophes in the directory name.

WWedge009 2026-08-03 github

There's a regression in Proton 11 where custom scenarios and missions downloaded from the workshop are no longer found. Reverting to Proton 10 resolves this.

The same applies for #477.
