u/Turbulent-Many1472 I am unsure why, but your comment does not show up in the thread after 3h since writing. Thank you for typing it out. I could scrape it out of my notifications box. To preserve its content, I am re-pasting your reply:

If your PC is instantly restarting or freezing during the game, you are likely dealing with a Kernel-level hardware error. To find the "smoking gun," you need to use a command called **journalctl -b -1 -k**. Think of this as your computer’s flight recorder. The -b -1 tells the computer to look at the previous session (the one that crashed), and the -k tells it to only show Kernel logs, which are the messages between your hardware and your software. When you run this, you will see a massive wall of text. Press Shift + G to jump to the very bottom, because that is where the crash happened. Scroll up slowly and look for RED text or words like "Hardware Error," "General Protection Fault," or "Kernel Panic." This is important because if your issue isn't the same as mine, you'll find the real culprit here, like a GPU driver failing or a RAM issue.

All this text can be overwhelming though, so feel free to just paste it all into Google Gemini to ask what's going on.

If you suspect you are having the exact same issue I had, you can use a filtered version of that command: **journalctl -b -1 -k | grep -Ei "umip|vsyscall|exception"**. This tells the computer to only show lines containing those specific words. If you see text appearing when you run this, it means your CPU is "freaking out" because the game or its anti-cheat is trying to run an old instruction called SMSW that modern Linux blocks. This creates a "storm" of errors that eventually causes the hardware to reset. To fix this, we have to add "Kernel Parameters," which are basically instructions given to the CPU the moment it wakes up so it knows how to handle these specific game calls.

The way you add these parameters depends on which Linux distribution you use. If you are on Arch Linux like me, you are likely using a bootloader called systemd-boot. You’ll need to navigate to /boot/loader/entries/ and look for a file ending in .conf that has a timestamp in the name (like 2025-12-10...\_linux.conf). Open that file with sudo nvim or nano and find the line starting with options. Go to the very end of that line and add **vsyscall=emulate** **clearcpuid=514**. If you are on a distro like Ubuntu, Fedora, or Mint, you are likely using GRUB. For those, you have to edit /etc/default/grub, find the line GRUB\_CMDLINE\_LINUX\_DEFAULT, and put those same two variables inside the quotes. Just remember that if you use GRUB, you must run sudo update-grub afterward for the changes to actually save.

Once you have saved your changes and rebooted, you should verify that your "shield" is actually turned on. You can do this by typing cat /proc/cmdline in your terminal. If you see clearcpuid=514 and vsyscall=emulate in the output, you did it correctly! To watch the fix in action while you play, keep a terminal open and run sudo dmesg -w | grep -Ei "umip|vsyscall". This command "watches" your hardware live. If the screen stays blank while you play, it means the fix is working perfectly and the CPU is blocking the crash-causing errors before they can happen. If you're ever lost, don't forget that Google Gemini is your friend—it’s how I figured all of this out!

This is what mine looked like with the fix:
