Subject: ZEN: Set default max map count to (INT_MAX - 5)
|
|
|
|
Per [Fedora][1], they intend to change the default max map count for
|
|
their distribution to improve OOTB compatibility with games played
|
|
through Steam/Proton. The value they picked comes from the Steam Deck,
|
|
which defaults to INT_MAX - MAPCOUNT_ELF_CORE_MARGIN.
|
|
|
|
Since most ZEN and Liquorix users probably play games, follow Valve's
|
|
lead and raise this value to their default.
