I don't use Lutris due to it's tendency to break stuff sometimes, all it's doing is managing a wine prefix. Some people like to have one single wineprefix with everything in it, I prefer one dedicated for each game. Have Ubuntu on a spare laptop, apt-get wine, wine64, winetricks. Use wintricks to create a new wine64 prefix for FFXI, the used winetricks to put the required libraries inside. Copied the FFXI installer to a temp folder under the c folder inside the prefix. Winetricks and launch explorer, double click on the install and it installs just like on windows. Same for windower, then make sure that atomos's dx9 proxy is inside the pol folder and it works cause dxvk is magical.
Lutris tries to automate all that, and it works usually, but when it breaks you need to spend awhile debugging why it broke. With FFXI not only are we installed a very old game (DX8), we are also trying to install windower on top of it with all the addons and so forth that requires.
