Thanks I searched and somehow didn't find those...
It might be useful to mention though since most games ran on wine instead of proton are 32 bit.
When you have wine/wine64 binaries and a wine prefix in win64, you can just use winepath for determine correctly who architecture directory like this:
# 32bits
WINEPREFIX=/path/to/prefix wine winepath -u 'c:\\windows\\system32'
# 64bits
WINEPREFIX=/path/to/prefix wine64 winepath -u 'c:\\windows\\system32'
That's how the setup_dxvk.sh script worked...
WINEPREFIX=/path/to/prefixx1 2023-03WINEPREFIXx1 2023-03WINEPREFIX=/path/to/wineprefixx1 2023-03
The x64 dlls should probably be going into the syswow64 folder and x32 dlls to the system32 folder.
