For those brave enough to attempt to get more Windows games to run through Steam Play, Protontricks is a handy solution and it's been forked.
As the GitHub page says:
This is a simple wrapper script that allows you to easily run Winetricks commands for Steam Play/Proton games. This is often useful when a game requires closed-source runtime libraries that are not included with Proton.
You might be wondering why it was forked, well, it seems the original creator has decided to pack up shop and leave it all behind. So thankfully, the community has already picked up from where it left off.
The developer of this newly forked project said this on Reddit about their newer version:
I've refactored the code and incorporated new fixes and missing features. Most notably the script now detects custom Proton installations and game-specific Proton versions (eg. if you have configured a custom Proton installation for one game), and the script can now be installed and updated using pip. A more detailed changelog can be found here.
Always fun to see what tweaks people can come up with, to make gaming on Linux a better experience however people decide to do it.
Hopefully as Steam Play and everything it includes like Wine, FAudio and DXVK mature, less little fixes will be needed. The less people have to configure and tweak, the more likely we are to win over a larger amount of people to try Linux gaming.
