Overview
Lord of Mysteries runs on Unreal Engine 5 with high-detail Lumen lighting, Nanite geometry, volumetric fog, and ray-traced reflections enabled by default on PC. This page lists the published requirements for both closed beta rounds: the PC-only Crimson Test (February 2026) and the first cross-platform Gray Fog Test (June 2026), which adds official desktop, laptop, Android, and iOS specifications. All figures are beta specifications and may change before the full launch on PC and mobile. Final-release system requirements have not been announced.
Crimson Test Minimum (PC)
OS: Windows 10 64-bit or Windows 11 64-bit.
CPU: A current-generation quad-core processor (community testing commonly cites the Intel Core i5-9600K and AMD Ryzen 5 3600 as floor-level acceptable parts, since the studio published only a recommended tier and no official minimum).
RAM: 16 GB minimum.
GPU: NVIDIA GeForce RTX 2060 (6 GB) or equivalent AMD Radeon RX 5600 XT class card.
Storage: SSD strongly recommended; the test client occupies roughly 50 GB.
Network: Stable broadband connection. The Crimson Test is a Mainland China-region online test; players outside the region typically need a network booster to maintain a usable ping.
Crimson Test Recommended
GPU: NVIDIA GeForce RTX 3070 Ti or AMD Radeon RX 6800 or above.
CPU: Intel Core i7-12700 / AMD Ryzen 7 5800X or better.
RAM: 32 GB for streaming-heavy zones like central Tingen during peak hours.
Storage: NVMe SSD; HDD installs are not supported.
macOS
macOS is not supported in the Crimson Test build. The studio has not publicly committed to a Mac client for launch.
Gray Fog Test Official Specifications (PC)
Ahead of the Gray Fog Test, SPARK NEXA published official minimum and recommended device requirements across four PC tiers: desktop and laptop, each with a minimum and a recommended row. These are the current authoritative PC figures for the Gray Fog Test and supersede the earlier single-tier numbers.
Desktop
Component | Minimum | Recommended |
|---|---|---|
Operating System | Windows 10/11 64-bit | Windows 10/11 64-bit |
Processor | Intel Core i7-7700 or AMD Ryzen 5 3400G | Intel Core i7-12700 or AMD Ryzen 7 7700X |
Graphics | NVIDIA GTX 1060 (6 GB) or AMD RX 480 | NVIDIA RTX 3070 Ti or AMD RX 6800 |
Memory | 16 GB RAM | 32 GB RAM |
Storage | At least 80 GB free space | At least 80 GB free space |
Laptop
Component | Minimum | Recommended |
|---|---|---|
Operating System | Windows 10/11 64-bit | Windows 10/11 64-bit |
Processor | Intel Core i5-11400H or AMD Ryzen 5 6600H | Intel Core i7-13700H or AMD Ryzen 7 8840HX |
Graphics | NVIDIA RTX 3050 (6 GB) or AMD RX 5600M | NVIDIA RTX 4070 or AMD RX 6850M XT |
Memory | 16 GB RAM | 32 GB RAM |
Storage | At least 80 GB free space | At least 80 GB free space |
Note: the official FAQ states that a device which does not meet the minimum specification cannot download the full game package for the test. Storage for the Gray Fog Test is at least 80 GB, which supersedes the earlier 90 GB figure carried over from the Crimson era.
Gray Fog Test Official Specifications (Mobile)
The Gray Fog Test is the first round to open iOS and Android alongside PC, and SPARK NEXA published official mobile device requirements for both platforms.
Android
Component | Requirement |
|---|---|
Operating System | Android 7.1 or higher |
Memory | 8 GB RAM or higher |
Processor (minimum) | Qualcomm Snapdragon 7 Gen 2 or higher |
Processor (recommended) | Qualcomm Snapdragon 8 Gen 2 or MediaTek Dimensity 9200 or higher |
iOS
Component | Requirement |
|---|---|
Operating System | iOS 15 or higher |
Device (minimum) | iPhone 12 Pro (A14 chip) or newer |
Device (recommended) | iPhone 14 Pro (A16 chip) or newer |
Display Features
NVIDIA DLSS upscaling is supported. AMD FSR 2 / 3 support has been mentioned in early show footage but is not formally confirmed for the Crimson Test build. Ray-traced shadows and reflections can be toggled per-feature; the cathedral interiors and gas-lit streets in Tingen benefit most visibly from RT.
Caveats
These specs reflect the Crimson Test only. The game is in active development and the launch-window minimum may rise (additional zones and effects) or fall (engine optimisation passes) before global release. Always check the most recent developer Q&A or the Release and Platforms page for the latest published numbers before buying hardware specifically for this game.
Gray Fog Test (June 2026): First Mobile Public Test
A low-memory mode is planned to be available at launch, intended to help the game run on more modest hardware, with further optimization passes planned to follow afterward. This is described as a plan rather than a finalised specification, and exact details have not yet been published.
The Gray Fog Test (灰雾测试), launching on June 26, 2026, is the first public test that includes iOS and Android clients alongside PC. SPARK NEXA confirmed the cross-platform scope on May 22, 2026 and published the full set of official PC, Android, and iOS specifications shown above. Players who want to test on mobile should sign up through the official site questionnaire. A device below the minimum specification cannot download the full test package.
