GSC Game World released update 2.0.6 for S.T.A.L.K.E.R. 2: Heart of Chornobyl on September 18, 2026. This patch, which carries the version ID 1.022 on PlayStation 5, focuses on resolving high-priority stability issues and technical regressions following the massive 2.0 “Back to the Zone” expansion.

Technical Stability and AMD GPU Fixes

The primary objective of version 2.0.6 is the resolution of multiple high-priority crash issues reported by the community after the game’s recent content launch. Specifically, the update backports several targeted fixes for crashes occurring on AMD GPUs, which had seen a spike in instability following the engine transition.

These stability improvements are a follow-up to the August 20, 2026, update that accompanied the “Cost of Hope” DLC. That milestone update shifted the game to Unreal Engine 5.5.4, and version 2.0.6 serves as a maintenance build to refine performance on this engine branch.

Mod Compatibility and Developer Advisory

Due to the technical nature of these stability fixes and the recent engine migration, GSC Game World has issued an official advisory regarding community-made modifications. Players who encounter crashes or performance hitches after installing patch 2.0.6 are recommended to disable all active mods to ensure compatibility with the updated build.

Steam Upgrade Discounts

In addition to the technical fixes, a limited-time promotion is available. Until September 30, 2026, Steam is offering a 30% discount on Deluxe and Ultimate Edition upgrades. This provides a window for standard edition owners to access the “Cost of Hope” DLC and other expansion materials at a reduced price following the 2.0 update cycle.

Key Changes in Update 2.0.6 (PS5 1.022)

• Resolved multiple high-priority crashes reported after the 2.0 content launch.
• Implemented specific stability backports for AMD GPU configurations to prevent hardware-specific crashes.
