Summary

Performance Beta Overview

This Steam-only Open Beta introduces significant performance optimizations for Cities: Skylines II. The primary focus is on rendering efficiency through improved LOD (Level of Detail) models for nearly all base game buildings, which should specifically benefit players on lower-end hardware.

Technical & Visual Updates

Beyond LOD improvements, the update refreshes the game's upscaling technology suite, including support for DLSS, FSR3, FSR 4, and XeSS 3. A minor visual addition includes new texturing under roads. Note that due to fundamental changes to Virtual Texturing, players opting into this beta branch will be required to perform a full redownload of the game assets.
