Captain's Diary #56: How we made products rendering 20× faster

Welcome everyone to today's edition of Captain's diary. I am Captain Marek and today I will be talking about some serious performance improvements we've done over the past few months. Are you ready for 20x faster products rendering?

Before that, I have an important announcement. Update 4.2 is nearly finished and will be released on the 20th of July! The key new features to look forward to are:

  • An in-game COI Hub integration for mods, maps, and blueprints.

  • Universal wagons for trains that can carry all 3 major types of cargo.

  • More train track pieces like 2-tile s-bends or grade changes.

  • Train waypoints with allow/deny options.

  • Ability for trains to autonomously go forward and reverse on bi-directional tracks if that's the shortest path.

  • New statistics for all products showing detailed usage breakdown.

  • Performance optimizations described in today's diary.

  • And more!
