-----UE5 official recommended
Windows 10 64-bit version 1909 revision .1350 or higher, or versions 2004 and 20H2 revision .789 or higher.
Quad-core Intel or AMD, 2.5 GHz or faster
8 GB RAM
DirectX 11 or 12 compatible graphics card
- DirectX 11: Latest drivers
- DirectX 12: Latest drivers
- Vulkan: AMD (21.11.3+) and NVIDIA (496.76+)
-----UE5 official minimum
Windows 10
Direct X End-User runtime (June 2010)
Some features have different requirements (no idea if used in Kalyskah)
Lumen Global Illumination and Reflections
|
Software Ray Tracing:
- Video cards using DirectX 11 with support for Shader Model 5
Hardware Ray Tracing:
- Windows 10 with DirectX 12 support
- Video cards must be NVIDIA RTX-2000 series and higher, or AMD RX-6000 series and higher
|
Nanite Virtualized Geometry
|
|
Virtual Shadow Maps
|
|
Temporal Super Resolution
|
Runs on any video card that supports Shader Model 5, but the limit of 8UAVs per shader has performance implications. Temporal Super Resolution shaders compile with 16bit types enabled on D3D12 that supports Shader Model 6. |
Typical development PC used at Epic
- Windows 10 64-bit (Version 20H2)
- 64 GB RAM
- 256 GB SSD (OS Drive)
- 2 TB SSD (Data Drive)
- NVIDIA GeForce RTX 2080 SUPER
- Xoreax Incredibuild (Dev Tools Package)
- Six-Core Xeon E5-2643 @ 3.4GHz

In reality, the development PC honestly is the one that may have to be considered a good guideline, not the minimum requirements.
Typically to see if the performances are OK, developers look at their own computer.
Unfortunately, to make them be able to develop faster, those tend to be bigger than the basic (even the average) computer people have at home (the ones at Epic seems not to exaggerate too much, but notice the 64GB RAM, and that the processor is a Xeon). I remember years ago some conversation with a developer who pointed out that problem himself.
For a game like Kalyskah, I would imagine and expect that the memory is less of a problem, the graphic card is more the trick.
