If you're a fan of turn-based RPGs and dying to try Clair Obscur: Expedition 33, but are held back by the fact that you don't use Windows, I have good news for you. It turns out that the Linux experience is surprisingly viable , allowing users of Steam Deck and Linux-based distributions to dive into this world without any hassle.

To ensure the game runs smoothly, the key lies in using Proton, Valve's tool that works its magic. While some might think configuring games on Linux is a headache, in this case, the gameplay is incredibly fluid , and for many users, simply pressing the play button is enough to begin the adventure.

Let's talk about the hardware. It's been proven that the game runs wonderfully even on high-end hardware, such as the RTX 4090. However, let's be realistic: performance can be somewhat hampered because Nvidia's Linux drivers aren't always as optimized as we'd like. Even so, this doesn't prevent the game from being perfectly playable and feeling smooth at all times.
