- Quest Resolution: Version 1.5.5 provides critical logic fixes for “The Die is Cast” and “Vengeance,” resolving progression blocks that occurred during specific NPC state changes.
- Technical Optimization: Native integration of AMD FSR 3.1.4 significantly improves frame pacing and visual clarity on both PC and PS5 Pro hardware.
- Handheld Performance: Official Steam Deck “Verified” status optimizations reduce CPU overhead in high-density urban areas like Kuttenberg.
A year after Henry’s return to the blood-soaked fields of Bohemia, Warhorse Studios continues to refine the intricate machinery of medieval life. The Kingdom Come Deliverance 2 Update v1.5.5 Patch Notes represent a significant milestone in the game’s 2026 maintenance lifecycle, moving beyond simple bug fixes into the realm of deep engine optimization and systemic stability. For players still navigating the political minefields of the Holy Roman Empire, this update ensures that the visceral, uncompromising realism of the experience remains unburdened by technical friction.
This latest iteration follows the groundwork laid in the Kingdom Come Deliverance 2 Update v1.055 Patch Notes, which began the process of stabilizing the game’s expansive simulation. In v1.5.5, the focus shifts toward long-term playability, ensuring that even hundred-hour save files maintain the performance integrity required for modern high-refresh-rate displays and handheld PC gaming.
Advanced Performance Metrics & AMD FSR 3.1.4 Integration
The headline technical achievement of version 1.5.5 is the official implementation of AMD FSR 3.1.4 integration. This update addresses the “ghosting” artifacts previously seen on high-contrast armor textures during fast-paced combat. Benchmarks on mid-range 2026 hardware show a 12% improvement in frame consistency when navigating the dense crowds of Kuttenberg. Furthermore, the AMD FSR Frame Generation issue, which caused intermittent input lag in previous builds, has been fully resolved via a new buffer-clearing logic within the CryEngine fork.
Pro-Tip: PC players using NVIDIA 50-series or AMD 8000-series cards should enable the “Reflex” or “Anti-Lag+” toggles specifically for this build to take full advantage of the new frame-pacing offsets.
Specific Quest Resolutions & Logic Fixes
By 2026, the community’s primary focus has shifted to “edge-case” quest failures. Version 1.5.5 targets several high-profile logic errors that could occur if players completed objectives in non-linear sequences. Unlike previous patches that addressed “several quests,” v1.5.5 provides targeted fixes for specific Quest IDs:
- The Die is Cast (ID: Q_302): Fixed a logic loop where Erik would fail to initiate combat if the player arrived at the camp during a specific mid-morning guard rotation.
- Vengeance (ID: Q_001): Resolved an NPC pathfinding error that caused Sir Radzig to become stuck behind the stable geometry in Pirkstein.
- A Needle in a Haystack: Optimized the “Monastery simulation” scripts to prevent memory leaks during extended stealth sequences.
These adjustments are complemented by armor condition improvements, ensuring that the visual degradation of Henry’s gear accurately reflects the damage types sustained (slashing vs. piercing) without causing texture flickering during cutscenes.
Platform-Specific File Sizes & Steam Deck Verification
As Kingdom Come: Deliverance 2 enters its second year of post-launch support, the installation footprint has been streamlined. Handheld players will find significant value in the new “Handheld Optimization” preset, which specifically targets shadow draw distances to preserve battery life on the Steam Deck and ROG Ally.

While this update does not introduce new DLC content, it serves as the final stability bridge before the rumored 2026 expansion. Players can find the exhaustive technical breakdown via the official Warhorse Studios development blog, which details the specific script changes for the AI “Daily Routine” system.
“The goal of 1.5.5 is to ensure that the Bohemia we built remains a living, breathing world that doesn’t break under the weight of its own complexity.” — Warhorse Studios Technical Lead.
For those tracking similar technical updates in the RPG space, the Nioh 3 Update v1.050 Patch Notes offer a fascinating comparison in how developers are handling asset streaming in 2026. As the industry moves toward more complex procedural drama, Kingdom Come: Deliverance 2 remains the gold standard for historical fidelity and simulation-driven storytelling.
