SimRail Update - 17.04.2026

Dear Players,

As promised, today we're releasing another SimRail update, introducing a very important improvement – ​​mipmap (texture) streaming. 😎🚂

This feature allows you to reduce graphics card memory (VRAM) usage while simultaneously increasing the resolution of close-up textures on low-end hardware. 💻🕹️

The new option is enabled by default and replaces the previous texture resolution selection – if you experience issues or performance drops, you can disable it in the settings and revert to the old settings. We'd appreciate your feedback on this matter. 👨‍🔧

We've also improved daylight by adding sun reflections from the ground, in preparation for the introduction of Screen Space Global Illumination. 🛤️

Shadow resolution has also been increased at high graphics settings, and the shadow draw distance has been slightly extended at ultra settings. 🏡

Cheers!

SimRail Team
