From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Is it only when playing this specific game, or do you have that in general, like when playing Steam games or modeling something in Blender?
For me it sounds like a hardware issue. The GPU is pretty old (age-wise, ignoring performance). Some electronics will degrade over some time and just stop working. That's my guess.
Also, two 4k-monitors sounds like torture for a card like this :D
Maybe install/ live-USB a completely other distro on a second drive and replicate this situation. Use default Ubuntu, Mint or Fedora, they have a different DE/ compositor and some other different underlying stuff.
If everything works fine, you know it's probably KDE, and if you have the same issues, it's a hardware problem and you have to repair/ replace something.
Don't forget to update me on this situation :)
I think the GPU is old, but it works no issue. It's very powerful and has no issue running these two monitors. Some other folks said it could be due to the compositor on kde directing all of its attention to the monitor here the game is. Also, I switched to HDMI on the monitor and now the issue is much, much better.
