- Multithreading for player sync, greatly improving per-player performance on multiplayer servers
- Added cpu affinity settings for main thread and server loop (set the index of the core to use or -1 for auto)
- Changed default compression level for screens from 6 to 2, greatly improving server load in exchange for a little bit more network bandwidth (existing servers should change it manually in server.ini)
- Fixed random weird invisible characters in Huds (and possible CTD) when using multiple huds
