Permafrost is rendered in Unreal Engine with dynamic volumetric snow, blizzard weather cycles, and sub-zero particle effects. Ensuring smooth performance is vital when dodging wolf ambushes.
This guide provides official hardware specifications, recommended Steam Deck settings, and fixes for known Early Access startup glitches.
1. Official PC System Requirements
| Specification | Minimum Requirements (1080p 30 FPS) | Recommended Requirements (1080p 60 FPS) |
|---|---|---|
| Operating System | Windows 10 (64-bit) | Windows 11 (64-bit) |
| Processor (CPU) | Intel Core i5-6600K / AMD Ryzen 5 1600 | Intel Core i7-9700K / AMD Ryzen 7 3700X |
| Memory (RAM) | 16 GB RAM | 16 GB RAM (Dual Channel) |
| Graphics (GPU) | NVIDIA GeForce GTX 1060 (6GB) / AMD RX 580 | NVIDIA GeForce RTX 2070 / AMD RX 6700 XT |
| DirectX Version | Version 12 (DirectX 12 Agility SDK) | Version 12 |
| Storage | 35 GB available space (SSD strongly required) | 35 GB available space (NVMe SSD) |
Crucial Hardware Note: Installing the game on a traditional mechanical Hard Disk Drive (HDD) causes severe texture pop-in during blizzards and prolonged loading screens. An SSD is mandatory.
2. Optimal Steam Deck Settings (Solid 40 FPS Profile)
Permafrost runs smoothly on Valve’s Steam Deck handheld with these fine-tuned graphical presets:
- Resolution: 1280 x 800 (Native 16:10)
- Refresh Rate & Frame Limit: Set SteamOS to 40 Hz / 40 FPS limit (delivers double battery longevity compared to 60 FPS).
- Upscaling (FSR): AMD FSR 2.2 set to Quality.
- Volumetric Fog & Snow Particles: Set to Low. (This single setting saves ~22% GPU overhead during heavy blizzards).
- Shadow Quality: Medium.
- View Distance: Medium.
- Texture Quality: High.
3. Fixing the “Windows Smart App Control” Launch Error
Some Windows 11 users report that launching Permafrost results in an instant crash or a blank black screen. This occurs because Windows Smart App Control mistakenly flags the peer-to-peer multiplayer component:
- Press
Win + Sand search for Windows Security. - Navigate to App & browser control -> Smart App Control.
- Under Exclusions, add
Permafrost.exelocated within your Steam installation folder (steamapps/common/Permafrost). - Restart Steam and launch again.
