Apart from what others already replied, a native game can run on SLR.
If it is being run without SLR, that would mean that you are using your distro’s system libraries, which you would find in places like /lib and /usr/lib.
If it is being run on SLR, then it is using the libraries that Steam downloaded in the location the SLR is installed.
Ok thanks! Is it related to proton or is it just for native games?
