Bottles

Bottles is an easy way to install games and other programs that don't have an install script in Lutris. Some people even prefer it for games that do have a Lutris script. It comes with a nice and clean UI, and has many features like LatencyFleX integrated. It can easily be installed as a Flatpak, and comes with the Flatpak sandboxing by default.

The wine prefixes (where your programs are stored) are in ~/.var/app/com.usebottles.bottles/data/bottles/bottles/<prefix_name>, where <prefix_name> is the name that you gave to the bottle.
