May i also add i tested GEPROTON latest, proton11 beta and a bunch of cachy protons
Resolved by adding the steamdeck flag to proton. Still sad to see
@ReubenPercival I checked a bit on my 4060 mobile, and outside a single short-lived stutter in the first mission, I didn't run into any issues, this with 595.71.05, proton 11, and without changing launch parameters. Card generation, graphics settings and driver versions are all possible factors so it'd be good to know your graphics settings.

try play for an hour long
its fucked and will make your driver hang, it will also vram ;eak
System
Observed behavior
The menus work, but the game intermittently freezes when entering a battle or shortly afterward. The tank/game audio may loop, and the game needs to be terminated manually.
The issue occurs both when playing solo and in a party, across different battle attempts.
There was one successful complete match on October 22, so this is not a consistent startup failure. However, multiple freezes recurred on October 23.
Kernel diagnostics
The failed sessions correlate with repeated NVIDIA Xid 13 errors, including:
SKEDCHECK19_CTA_REGISTER_CONSUMPTION failed
I also tested alternative Proton configurations, including VKD3D_CONFIG=single_queue and disabling NVIDIA NVAPI, without a reliable fix.
I'm not claiming that these messages establish the root cause, but they may help correlate NVIDIA driver failures across different GPUs and Proton configurations.
Game engine logs, Proton diagnostics, and kernel evidence have been preserved locally. I can provide relevant redacted logs if they would help investigate this further.

have you tried latest nvidia driver?
It seems to have resolved SOME fo this isue
SOME
Hi AtomicKaiser! Thanks for the suggestion, I appreciate it!
I'm currently running Fedora KDE 44 with a GTX 1080 Ti (Pascal) and NVIDIA driver 580.178.04 from RPM Fusion.
I noticed that NVIDIA released 580.196.07 on October 21, but the updated 580xx packages don't appear to be available through RPM Fusion for Fedora 44 yet.
My freezes consistently correlate with this NVIDIA kernel error:
Xid 13: SKEDCHECK19_CTA_REGISTER_CONSUMPTION failed
The game works normally in the menus, but freezes when entering battles, across multiple maps and modes. Do you happen to know which NVIDIA driver version resolved the issue for other users, and whether they were experiencing this same Xid 13 error?
I'd prefer to keep the distro-managed driver installation intact while investigating, but I'm definitely interested in testing an updated compatible driver when it becomes available.
Thanks again for your help it is very much appreciated.

Have you tried to swap proton version , clean cache and prefix?
Hi
Yes, I've already tested different Proton versions, including Proton Experimental and 11.0-2e, as well as a fresh prefix and Steam Overlay disabled. Funny though, before i had to use Proton Experimental on my build for a long time as the most stable solution and it did work flawlessly, until Halloween battlepass update.
I also tested VKD3D_SHADER_CACHE_PATH=0 to isolate the shader cache without deleting the existing cache. Unfortunately, the game still froze when transitioning into Battle, followed by the same NVIDIA kernel error:
Xid 13: SKEDCHECK19_CTA_REGISTER_CONSUMPTION failed
The menus remain stable, but the issue reproduces across multiple maps and game modes. I haven't manually deleted the existing shader cache as part of that isolation test. I've preserved the relevant engine, Proton and kernel logs if they'd help.
Thanks again for looking into this!

Hmm. tried fully open source drivers eg noeuva ( sorry for spelling) ?
Thanks for following up, Kaiser! I really appreciate your help. And no worries about spelling i appreciate the input and help.
I haven't tested Nouveau/NVK. I'm running a GTX 1080 Ti (Pascal), and I'm aware of the performance limitations with Nouveau on this generation, particularly GPU reclocking.
Since this is my daily Fedora system and the proprietary NVIDIA driver works well with my other games, I'd prefer not to replace the current driver stack just for this test.
The issue is specifically with WoT HEAT: the menus are stable, but the game freezes during matches, with NVIDIA reporting Xid 13 / SKEDCHECK19_CTA_REGISTER_CONSUMPTION in the kernel logs.
I've already tested different Proton versions and a clean prefix, but the issue persists. Do you think there's another targeted diagnostic we could try with the proprietary NVIDIA driver, or any additional logs that would help narrow down the cause?
Thanks again for taking the time to look into this as well as your time, effort and suggestions and help. It is much appreciated.

Very unclear Linux Support in the future from the developers via their discord server.
In a support ticket i asked about GNU/LINUX support and they said " No, Thee game is currently officially support on Windows OS only."
They did say " the game is available on steam , including the steam deck"
This is a contradiction and im not sure if they will continue to support Linux
I also got fps dips and very bad 1% lows on
Cachy OS latest 7.1rc kernel , mainline 7.0.10 and cachy kernel 7.0.10
rtx 5050 with 610 driver
Core 5 210H
ive tried scx
beerland, rustland, lavd, none
My gpu driver also died many times when playing this game which never happens on other games.
