STALKER 2: Heart of Chornobyl - system requirements (minimum and recommended)

STALKER 2: Heart of Chornobyl is one of the most demanding games of recent years: the Unreal Engine 5, a huge seamless world of 64 km² and photorealistic graphics require serious hardware. GSC Game World has published the final system requirements broken down into four presets - from minimal to Epic. Let's look at what kind of PC is needed for the Zone in 2026.

Minimum system requirements STALKER 2 (Low, 1080p / 30 FPS)

Minimum settings are rated at 30 FPS at 1080p on low settings. Please note: for a first-person shooter, 30 FPS is uncomfortably low, so you should treat a “minimal” PC as an entry point, not a target configuration.

Medium settings (Medium, 1080p / 60 FPS)

Recommended system requirements (High, 1440p / 60 FPS)

This is what the developers call the recommended preset: 60 FPS in 1440p resolution on high settings - the game looks and works as intended.

Epic settings (2160p / 60+ FPS)

For maximum 4K graphics you will need a top-end graphics card. Ryzen X3D processors (for example, 7800X3D) perform excellently - a large cache significantly levels out the frametime in UE5 games.

How much does STALKER 2 weigh and why does it need an SSD?

The game takes up about 160 GB , and the SSD is not listed in the requirements for show: The Zone constantly loads textures, NPCs and world objects. Freezes, stutters, and long loading times are possible on HDDs, even on a powerful video card. Optimally - NVMe SSD with extra space for patches and mods.

Will STALKER 2 run on a weak PC or laptop?

Honest answer: the game will not run on weak hardware. Integrated graphics are not supported - you need a discrete video card at least GTX 1060 6 GB. But there are ways to squeeze out performance:

• enable upscaling: the game supports DLSS 3 with Frame Generation (for RTX 40 series), FSR and XeSS;
• reduce shadows, lighting and drawing distance - they load the GPU the most;
• update your video card drivers - GSC and hardware manufacturers regularly release optimizations;
• close background applications: all 16 GB of RAM are critical for the game;
• The game launches on Steam Deck, but there are some issues with stability - it’s better to look at the latest community reports.

On which platforms is STALKER 2 available?

• PC (Windows 10/11) - Steam, GOG, Epic Games Store, GSC official website;
• Xbox Series X|S - including Game Pass from day one;
• PlayStation 5 - released later, after the Xbox exclusive period.

On consoles, the system requirements are not relevant - the game is optimized for console hardware. There are no versions for Mac, PS4 and Xbox One and there are no plans.
