ServerManager-compatible NPS fork: keeps network improvements while ServerManager owns player limits and admission.

KadettNPSCompat

KadettNPSCompat is an unofficial, ServerManager-compatible modification of NetworkPerformanceSystem 1.14.0.

It is not affiliated with or endorsed by MidnightsFX or the MidnightMods Thunderstore team.

What changed

Only NPS's Player Limit mechanism is disabled. It normally rewrites ZNet.RPC_PeerInfo, the same admission check that ServerManager needs to manage server-side characters. Leaving that method untouched lets ServerManager safely control player admission and the configured player limit.

All other NPS networking mechanisms remain in the build, including send scheduling, connection-loss handling, ownership tuning, routed-RPC filtering, station request routing, and allocation reductions.

Installation

  1. Remove the official MidnightMods-NetworkPerformanceSystem package from the server and every player profile. Do not run both packages together.
  2. Install KadettNPSCompat with Gale on the server profile and every player profile.
  3. Keep the player limit in ServerManager.yml. The NPS Player Limit configuration is deliberately ignored by this package.
  4. Start the server and confirm its log has no ServerManager Fatal error.

Compatibility

Tested with Valheim 1.0.16 / network version 40, BepInEx 5.4.2351, Jotunn 2.30.2, ServerManager 1.1.7, and NPS upstream 1.14.0.

Source and license
