Can your PC run In Falsus? Short answer: if it runs Windows 10 and was bought in the last several years, yes. These are the official system requirements from the Steam page, plus what the public demo tells us about real-world performance on laptops, Steam Deck, Linux, and Mac.
Official minimum requirements
| Spec | Minimum requirement | Recommended |
|---|---|---|
| OS | Windows 10 or newer (64-bit) | Windows 10+ (64-bit) |
| Memory | 8 GB RAM | — |
| DirectX | Version 11 | — |
| Storage | 8 GB available space | — |
| CPU | Not specified | Not specified |
| GPU | Not specified | Not specified |
lowiro published no CPU or GPU requirement at all — the recommended section only repeats the 64-bit OS line. That's a strong hint about how light the game is: In Falsus is a 2D rhythm + visual-novel title, not a 3D renderer. Compare that with most 2026 releases that demand a dedicated GPU just to boot.
What that means in practice
- Integrated graphics are fine. The demo renders 2D sprites, VN backdrops and note highways — workloads well within Intel Iris / AMD Radeon integrated GPUs.
- 8 GB RAM is the real floor. Close memory-hungry browser tabs before long sessions if you're at exactly 8 GB.
- Storage: budget the full 8 GB for the September 9 release; the demo itself is much smaller.
- Frame rate matters more than visuals. In a rhythm game, stable frame pacing beats raw resolution. If your machine is old, cap the frame rate and lower background effects in settings before blaming input lag.
- The demo is your benchmark. The free demo runs the exact same engine — if it plays smoothly on your machine, the full game will too.
Laptop checklist
- Plug in power — battery mode can cap CPU/GPU clocks and introduce stutter during dense note sections
- Close overlays (Discord, recording software) if you see dropped frames on FIELD notes
- Check your audio setup: high sample rates (32-bit/192 kHz) have caused launch issues — see the no sound fix
- If keys don't register together, that's usually keyboard ghosting, not the game — see keys not working
Steam Deck & Linux
There is no Deck Verified status and no native Linux build, but the community runs both through Proton:
- Steam Deck: playable with GE-Proton 10-32 or 11-1 (ProtonUp-Qt). Stock Proton can break intro video; no gamepad mapping exists, so plan for keyboard + touchpad. Full walkthrough: In Falsus on Steam Deck
- Desktop Linux: same GE-Proton advice applies; check ProtonDB for your distro
Mac
No macOS version exists or has been announced. Options for Mac users:
- Boot Camp on older Intel Macs (Apple Silicon Macs cannot Boot Camp)
- Stream from a Windows PC (Steam Remote Play / Moonlight)
- Wait — but don't hold your breath; lowiro's PC releases to date have been Windows + Steam only
