Mafia: The Old Country
+1
+1. Also overal bad performance and frame drops at random moments. Even when not a lot is hapening.
Happened to me too though for me I was experiencing subpar framerates on the lowest settings, FSR 3 and Frame generation
The Steamdeck is worse while it can run and play the game the same settings will get you a 30FPS experience providing you lock the framerate
While this part isn't really a Proton issue testing might suck as the game's DRM is aggressive and blocks users from accessing if it it detects multiple associated devices
Upon launching the game today, I got this:

Update, After tinkering around I found that disabling any upscaling and selecting native dlaa makes the game run far more stable.
I am also getting this runtime error upon launch:

I got the same error as you. After upgrading to Mesa 25.2 i got a different error message:
Quick google search - as i am not a programmer of any sort - indicates that both are connected to problems with compute shaders?

-- no logs were recorded using logging launch options
Symptoms
The game causes a complete system freeze and crash when running on Linux. This is caused by the game attempting to execute privileged CPU instructions
(SMSW, SGDT) which are intercepted by the kernel's User Mode Instruction Prevention (UMIP) feature. The emulation of these instructions is extremely
resource-intensive, leading to a CPU spike of over 80% and subsequent system crash. This is a software issue within the game itself.
The kernel log (dmesg) shows the following errors repeatedly before the crash:
1 umip: MafiaTheOldCoun[9440] ip:15caf8ef0 sp:c9fe10: SMSW instruction cannot be used by applications.
2 umip: MafiaTheOldCoun[9440] ip:15caf8ef0 sp:c9fe10: For now, expensive software emulation returns the result.
3 umip: MafiaTheOldCoun[9440] ip:155594c35 sp:c986e8: SGDT instruction cannot be used by applications.
4 umip: MafiaTheOldCoun[9440] ip:155594c35 sp:c986e8: For now, expensive software emulation returns the result.
Reproduction
- Launch "Mafia: The Old Country" on a Linux system with a UMIP-enabled kernel (standard in modern kernels) using Steam/Proton.
- Play the game for a short period of time.
- The system will reliably freeze and crash, requiring a hard reboot.
@OrigamiPaperCrane did it start at least once? Did you enable FSR in your upscaling options?
No, I've never reached any menu at all.
It's strange then, other games exhibit the exact same pattern on dmesg yet from my own memory (I had a 3800xt back in the day) they ran fine. All UE games exhibit this issue, no less!
@NyaomiDEV are you still getting gpu resets? if so, do they happen every time upon launching the game?
@marek-lach @Azonnali You need to provide as much information of your system as you can.
Kernel and gpu driver version, gpu, desktop environment, proton version used.
@OrigamiPaperCrane those umip dmesg messages are unrelated to the game not working. Your kernel, and rivers are old so I'd first try updating those to see if the game begins working for you.
@simifor Nope, I just reset all my save data and started from scratch without touching graphical settings. FSR is bugged. Probably XeSS too but idk.

Symptoms
Honestly this may be an issue with the game itself, tough to say - but:
Heavy frame drops when entering a cut-scene. Going from 90-120fps during gameplay and switching to a cut-scene drops the frame rate down to about 40fps (occasional sub 40).
Note: Uncapped fps cut-scene option is enabled in settings.
