Trainz 22 – SP6 Hot Fix 1

We’re pleased to announce the release of SP6 Hot Fix 1 for Trainz 22. This update is the direct result of working closely with our core users to address feedback around the memory monitoring system we fine-tuned in SP6, and ensuring a speedy turnaround to deliver improvements as quickly as possible.

Why the Hot Fix Was Needed

In SP5, we added code designed to help Trainz stay within desktop memory limits. While this system worked as designed, it became clear that some routes and locomotives were hitting these limits sooner than expected. In traditional game development pipelines, this would be addressed by the art team reworking content to reduce load. We do this with builtin content but with Trainz being a community-driven platform, it’s not realistic to expect millions of existing community assets to be reauthored.

That meant we needed another approach.

What’s Changed

For SP6 Hot Fix 1, we’ve:

• We've temporarily relaxed the memory limits to be far more permissive, allowing us to spend additional time gathering information on problematic scenarios and working with content creators to ensure quality outcomes.
  

These adjustments should mean a more consistent experience in line with SP5 across all routes.

What’s Next

Looking ahead, we will:

• Continue monitoring and tweaking the desktop memory limiter as more feedback comes in.
  

• Improve asset efficiency over time, particularly train vehicle assets, which we know can be memory-intensive and support this through:
  

  • Working with creators to educate and assist them in making more efficient assets.

  • Updating our content creation guidelines to better reflect modern heavy-weight assets.

  • Providing additional engine features to reduce memory usage in the heaviest assets.

A Better Balance for Everyone

The goal of these changes is to strike a balance: ensuring Trainz performs well across a wide range of hardware, while still enabling the creativity and scale that our community is known for.

We’ll keep listening, adjusting, and refining as we go. Thanks to everyone for their patience, testing, and passion that helps make Trainz stronger with every release.
