How do I run more than one game in the same wine prefix?

By default, umu-launcher sets the Proton verb waitforexitandrun when launching games, which will cause the current process to wait until an active wineserver process has exited. To run more than one game in the same prefix, you must disable this behavior for subsequent games by setting either PROTON_VERB=runinprefix or PROTON_VERB=run.

Also, it's important that the Proton or wine configuration for each nth game is equivalent except for the PROTON_VERB environment variable. Otherwise, unexpected behavior may occur. For example:

GAMEID=0 umu-run foo

GAMEID=0 PROTON_VERB=runinprefix umu-run foo

However, launching the second game with fsync disabled would be invalid:

GAMEID=0 umu-run foo

GAMEID=0 PROTON_VERB=runinprefix PROTON_NO_FSYNC=1 umu-run foo
