Released Proton 6.3-6

I’ve started making my Proton builds which are compiled directly from Valve’s Git repo. These are useful if you want to run non-steam games on Linux without needing to create a new partition with Micro$oft’s OS.


Update: Built Proton 6.3-6c, which has some minor fixes and I externally applied this patch to enable compatibility with some other games. (If it breaks compatibility with some games, please tell it to me).

Update 2: Repacked Proton 6.3-6c with the Steam compat files (will be located in the compat folder), to improve Steam support inside Proton.
