Schedule I v0.4.4: Weather Update Patch Notes (19th March 2026)

Schedule I's v0.4.4 Weather Update landed today, and according to the official Steam patch notes, it's one the solo developer has been sitting on for a while. Multiple new weather conditions can now occur randomly throughout the day in Hyland Point, which should do a lot for the game's atmosphere. If you've been spending hours running your operation under the same flat sky, that changes now.

The performance angle is worth flagging. New weather systems in games this size can tank framerates fast, but the developer says the new system carries almost zero performance impact, even during the heaviest visual effects. There's also a separate pass of rendering optimisations applied to existing parts of the game. That's a genuinely good sign for a title still in Early Access.

Credit where it's due: shipping a visually meaningful update without a performance cost is harder than it sounds, and the fact that optimisation was clearly treated as a first-class concern here rather than an afterthought says something. Full patch notes below.

Hi everyone,

The weather update is now fully released! There are several new weather conditions that can occur at random throughout the day. This update is one I've been excited about for ages - I think it adds a ton of life and atmosphere to Hyland Point.

We've worked really hard on optimisation for this update - the new weather system has almost zero performance impact, even during the most visually complex effects. We've also made a number of rendering optimisations to existing parts of the game. In our testing, FPS seems to be 5-10% **higher **compared to the previous version of the game.

• Fixed vehicle impacts not dealing damage to NPCs.
• Fixed a rare load ordering issue where grow lights would try to load in before suspension racks.
• Fixed frame spike when the first vehicle pathfinding calculation occurs.

I mentioned in my last post that there would be a lot of code refactoring happening in this update. My initial plan was to do a big round of refactoring now, and then do official mod support later this year. I quickly learnt that mod support is a massive influence on code architecture. If I had done a big refactor now without proper consideration for modding, I'd end up having to do an equally large rewrite in just a few months.

For this reason, I've decided to stagger the refactor over several updates in the first half of the year instead of doing it all at once. As each major game system is rebuilt and cleaned up, it will also simultaneously be prepared for mod support. This means that when we do enable mod support, it will be a much faster and seamless process.

Stay tuned!
