Summary
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!
