Sadly for many games the Windows version runs and looks better than the Linux version. That’s often because the Linux version is done by outside contractors whose contract expired. So while the Windows version will receive updates the Linux version lies stagnant.
See Tomb Raider 2013 for instance. The Windows version via Proton looks and runs much better than the native one.
I got our engagement rings from a gumball machine. And I didn’t even pay for those myself because I didn’t have the necessary 20 Cent coins. A passerby gave me three and didn’t accept a Euro in return.
