Lunarium System Requirements
Minimum and recommended PC specs for Steam and Epic Games Store.
Lunarium runs on Windows 10 PCs with modest hardware by modern standards. The official specs come from the Steam store page and apply equally whether you buy on Steam or the Epic Games Store — both versions are native PC builds from Lunarium Game Studio.
Use this guide to check your machine before the July 29, 2026 launch and to decide whether you need to lower settings for stable frame rates during busy boss fights.
Minimum requirements
These are the floor specs Imperfect Games lists for a playable experience at reduced settings:
| Component | Minimum spec |
|---|---|
| OS | Windows 10 |
| CPU | Intel i5 Quad-Core, 2.7 GHz |
| RAM | 8 GB |
| GPU | NVIDIA GTX 1050 Ti or AMD R9 285 |
| Storage | 5 GB available space |
An Intel i5 quad-core at 2.7 GHz covers popular chips like the i5-4430 or i5-7500 tier. The GTX 1050 Ti and R9 285 are entry-level discrete GPUs from the mid-2010s — common in budget gaming laptops and older desktops.
Eight gigabytes of RAM is tight by 2026 standards but matches what the developer tested against. Close background apps before launching if you sit near this minimum.
Recommended requirements
Recommended specs target smoother frame rates and headroom for future patches:
| Component | Recommended spec |
|---|---|
| OS | Windows 10 |
| CPU | Intel i5 Quad-Core, 3.0 GHz |
| RAM | 8 GB |
| GPU | NVIDIA GTX 1080 Ti or AMD RX Vega 64 |
| Storage | 5 GB available space |
The recommended CPU bump to 3.0 GHz helps during crowded encounters with multiple enemies and particle-heavy Resonance effects. GPU recommendations jump significantly — a GTX 1080 Ti or RX Vega 64 class card should handle 1080p at high settings comfortably.
Notably, RAM stays at 8 GB for both tiers. If you have 16 GB or more, Windows will cache assets more aggressively, which helps zone loading between the forest, castle, and archipelago areas.
Storage and install size
Lunarium requires 5 GB of free disk space. That figure covers the base game install; save files and shader caches add a small amount over time.
Install on an SSD if possible. Isometric ARPGs stream art assets frequently as you move between rooms, and an SSD reduces hitching when entering Temple hubs or boss arenas.
Operating system notes
Only Windows 10 is listed officially. Windows 11 generally runs Windows 10 titles without issue, but Lunarium Game Studio has not explicitly certified Windows 11 — community reports after launch will clarify compatibility.
There is no macOS or Linux build announced. Proton compatibility on Steam Deck may work post-launch, but treat handheld play as unsupported until players verify performance.
GPU equivalents
If your card is not named exactly in the store listing, compare approximate performance:
Minimum tier equivalents (1080p, low–medium):
- NVIDIA GTX 1650, GTX 1060 3 GB
- AMD RX 560, RX 570
- Intel Arc A380 (with updated drivers)
Recommended tier equivalents (1080p, high):
- NVIDIA RTX 2060, RTX 3060
- AMD RX 5700 XT, RX 6600 XT
Lunarium’s hand-drawn art style is less demanding than photorealistic AAA titles, but parry-focused combat needs consistent frame timing — aim for a stable 60 FPS where possible.
Performance tips before launch
- Update GPU drivers — especially on laptops with switchable graphics.
- Use fullscreen borderless if the game offers display modes; this reduces input lag on multi-monitor setups.
- Check the demo first — the Lunarium demo (Steam App ID 3525540) is a low-risk way to benchmark your PC.
- Read controls early — smooth combat depends more on input consistency than raw GPU power. See controls for key bindings.
