Heart of Chornobyl is finally getting a much-needed update. Fans have been waiting for stability improvements, bug fixes, and better gameplay performance—and it looks like Patch 1.5 will deliver just that.
GSC Game World, the studio behind the game, has confirmed that Patch 1.5 is in its final testing phase and will roll out soon. Whether you’re a returning player or someone who put the game on hold due to issues, here’s a complete breakdown of what to expect from the new patch.
Expected Release Date for Patch 1.5
Although there’s no official launch date yet, developers have shared that Patch 1.5 is expected to release by the end of June or early July 2025. It’s currently undergoing final polish and testing to ensure that the update does not introduce any new bugs.
The patch will release simultaneously across all platforms—Xbox Series X/S and PC.
What Patch 1.5 Aims to Fix
Over the past few months, players have reported several issues affecting gameplay, from unexpected crashes to visual glitches. Patch 1.5 addresses many of these problems and introduces a long list of fixes and improvements.
Bug Fixes
Here are some of the major issues the update plans to fix:
- Crashing during missions or open-world exploration
- Sound cutting out during dialogue scenes
- Enemies and NPCs getting stuck in terrain
- Inventory problems after loading a saved game
These are among the top complaints from the STALKER community, and GSC says they’ve prioritized resolving them for a smoother experience.
Gameplay Enhancements
Several gameplay tweaks are also part of this patch. The update will bring:
- Smarter enemy AI and patrol patterns
- Improved stealth mechanics
- Smoother weapon switching and reload timing
- Balanced combat difficulty in early game zones
Players should feel more in control during fights, and enemy encounters will be more strategic rather than chaotic or unpredictable.
Performance Boost and Technical Improvements

One of the biggest complaints from PC players, especially those on mid-range systems, has been poor performance. Patch 1.5 focuses heavily on technical improvements.
On PC

On Xbox Series X/S
- Targeted improvements to achieve a more stable 60 FPS
- Reduced loading times when entering new areas
- Better memory usage and crash prevention
These updates aim to make the game more enjoyable for both high-end and budget players.
Visual and Audio Upgrades
STALKER 2 already looks stunning, but Patch 1.5 will improve the game’s overall look and sound in subtle but noticeable ways.
Graphics
- More realistic lighting in night environments
- Improved rain and water effects
- Sharper textures and distant object rendering
Audio
- Fixed environmental audio dropouts
- Better volume control during indoor scenes
- More consistent ambient sound in open areas
These changes help players stay immersed in the game’s intense and moody world.
Improvements to Save Game System
Many players have had issues with lost progress due to save file corruption or broken autosaves. Patch 1.5 introduces some helpful changes:
- Safer autosave intervals
- Additional backup save slot
- Warning messages before overwriting manual saves
These small changes could save players hours of lost progress and make long play sessions less stressful.
