Linux Gaming Test: Rebel Inc. Escalation (Details in Description)

Note: Rebel Inc. Escalation does not have an official Linux support. The game may be unplayable on some distributions such as Fedora (This is from my experience.) despite Steam's Proton compatibility layer.
Hardware plays a major role in performance. Linux generally runs game faster than Windows but it may still be bad if your computer is old and/or outdated. In this video in particular, computer used is mid-tier, not a high-end nor low-end computer.
The game is recorded in full screen for maximum performance. The footage itself is recorded using OBS Studio.
Lastly, the Linux distribution used is Linux Mint Xfce 21.3.
