Blind Descent requires a 64-bit Windows operating system, a DirectX 12-compatible graphics card, and at least 16 GB of system RAM to run on PC. Pokuch and META Publishing built the subterranean Martian survival adventure on Unreal Engine 5 modern rendering APIs, meaning older DirectX 10 or DirectX 11 GPUs without DX12 feature support cannot run the client.
Official Blind Descent System Requirements
The official Steam store listing outlines the baseline hardware specifications for the PC version of Blind Descent. While older placeholder retailer pages once listed lower legacy specs, current Steam and developer announcements confirm that modern 64-bit hardware and DirectX 12 are mandatory.
| Hardware Component | Minimum Requirements | Recommended Requirements |
|---|---|---|
| Operating System | Windows 11 64-bit | Windows 11 64-bit |
| Processor (CPU) | Intel Core i3 | Intel Core i5 or higher |
| Memory (RAM) | 16 GB RAM | 32 GB RAM |
| Graphics Card (GPU) | DirectX 12 compatible GPU with 2 GB VRAM | DirectX 12 compatible GPU with 6 GB VRAM |
| DirectX Version | Version 12 | Version 12 |
| Storage Space | 40 GB available space | 40 GB available space |
| Network | Broadband Internet connection | Broadband Internet connection |
On GOG, the store page lists Windows 10 64-bit as compatible alongside Windows 11, but both platform pages agree that 64-bit architecture is strictly required.
Playtest and Demo Hardware Specifications
During public demo and alpha playtest phases, the development team published specific model-level hardware targets to help players test early builds. Storage footprints and component tiers slightly differ between test builds and store listings because optimization remains an ongoing process leading up to Early Access.
| Component | Playtest Minimum (Low Preset) | Playtest Recommended (Medium-High Preset) |
|---|---|---|
| Operating System | Windows 11 or latest version of Windows 10 | Windows 11 (latest version) |
| Processor (CPU) | Intel Core i3-10100 (or equivalent AMD) | Intel Core i5-12400 / AMD Ryzen 5 3600 and higher |
| System Memory | 16 GB RAM (DDR4 or higher) | 32 GB RAM |
| Graphics Card | Nvidia GeForce GTX 1080 Ti (or equivalent AMD) | Nvidia GeForce RTX 3060 12GB (or equivalent AMD) |
| Video Memory | 4 GB VRAM minimum | 12 GB VRAM recommended |
| DirectX | DirectX 12 exclusive | DirectX 12 exclusive |
| Storage Drive | 36 GB to 42 GB free space (SSD recommended) | 36 GB free space (SSD required) |
Older website entries previously referenced Unreal Engine 4 during early conceptual planning in 2019, but official playtest announcements confirm the game is actively built using Unreal Engine 5 technology.
Known Performance Issues and Developer Troubleshooting
Early test builds have revealed several hardware bottlenecks, particularly regarding memory consumption, driver compatibility, and specific GPU architectures.
Background RAM Management
The development team strongly advises that users playing with 16 GB of RAM close heavy background programs, such as web browsers, before launching the game. Unreal Engine 5 assets can push memory utilization high enough to cause stuttering or out-of-memory crashes on 16 GB systems running secondary tasks.
GPU and DirectX 12 Crashes
Because the engine runs exclusively on DirectX 12, entry-level or legacy cards without dedicated DX12 feature support (such as low-tier office cards with 2 GB VRAM like the GeForce GT 1030) fail during environment loading or crash back to the Steam client. Developer KyuKyu confirmed in community discussions that lowering graphical presets to the absolute minimum is required on lower-end cards, though updating graphics drivers remains necessary to prevent immediate launch failures.
Freezing on AMD Graphics Cards
Players testing high-end hardware—including top-tier AMD GPUs—have reported stuttering and freezes when approaching open subterranean cave zones. Developer staff confirmed that early demo builds experienced known stability issues specific to AMD GPUs. While developers continue rolling out patches to resolve engine-level stutter, keeping AMD Adrenalin drivers fully updated is required.
Submitting Crash Reports and Diagnostic Files
If your system meets the official requirements but the game client crashes or freezes, developers request diagnostic logs via the Steam Community Hub or the official Discord server:
- Press
Win + Ron your keyboard, typedxdiag, and press Enter. - Allow the DirectX Diagnostic Tool progress bar in the bottom-left corner to finish gathering hardware data.
- Click "Save All Information" to export your hardware profile into a text file.
- Report the issue on Discord or the Steam forums with a brief description, steps to reproduce the crash, and your DXDIAG file.
- In supported demo builds, players can also trigger the in-game reporting tool directly by pressing
F1, or by pressingEsc/Alt + B.
Frequently Asked Questions
What engine does Blind Descent run on?
Blind Descent is built using Unreal Engine 5 and runs exclusively on the DirectX 12 API.
Can I run Blind Descent on Windows 10?
Yes. Official playtest announcements and GOG documentation confirm the game runs on the latest 64-bit updates of Windows 10, although the developers recommend Windows 11 for optimal DirectX 12 performance.
Does Blind Descent support controllers?
Yes. Blind Descent includes full controller support, featuring compatibility for PlayStation 4 DualShock, PlayStation 5 DualSense, and the Steam Input API.
Will playtest or demo save progress carry over to Early Access?
No. Official playtest announcements state that playtest and demo save files will not carry over to the final release, because structural systems, balance passes, and underground narrative zones are actively evolving.
