The System Shock remake from Nightdive Studios was originally funded on Kickstarter, and after delays it was eventually released on May 30th, 2023 but two platforms have been missing - Linux and macOS.
Kinda shady considering this was a Kickstarter stretch goal.
If they use a natively supported graphics API, i.e. Vulkan there’s not really a difference between Linux binaries and Windows binaries ran through proton. The possibility of the Linux version running worse is also there because of likely less optimization done by the devs due to multiple versions having to be developed.
If some games run so well on Linux with Proton, imagine how well they could run on Linux if they were designed to.

Euro Truck Simulator 2 has a native Linux version but only the Windows version launched via Proton actually works on my Linux PC.
Usually that’s because Linux versions have been abandoned after Steam Machines flopped. Same is with Dying Light, iirc Borderlands 2 as well
