Duet Night Abyss targets modest midrange hardware on PC. If you have a recent quad‑ or hexa‑core CPU and a last‑gen midrange GPU, you’re in good shape. Below are the official minimum and recommended specs, plus the storage you should set aside before you install. You can install the PC version from its Steam page.

Duet Night Abyss PC requirements (official)

Component Minimum Recommended
OS Windows 7 64‑bit Windows 10 64‑bit
CPU Intel Core i5 (9th gen) / AMD Ryzen 5 2600X or above Intel Core i7 (10th gen) / AMD Ryzen 7 3700X and above
Memory 16 GB RAM 32 GB RAM
Graphics NVIDIA GeForce GTX 1060 / AMD Radeon RX 580 NVIDIA GeForce RTX 2060 / AMD Radeon RX 5700 XT
Network Broadband Internet connection Broadband Internet connection
Storage 32 GB available space 40 GB available space

If your rig sits between these tiers, expect to start at medium settings and scale up or down based on frame rate.

Windows version caveat (Steam client)

While the game’s minimum OS lists Windows 7, the Steam client only runs on Windows 10 or later as of January 1, 2024. If you’re still on Windows 7 or 8.1, you won’t be able to install or update the game through Steam. Tip: on Windows 10 or 11, you’re covered for both the recommended OS and the Steam client requirement.

Download size and disk space

Item PC size
Initial download About 15 GB
Installed space (minimum) 32 GB free
Installed space (recommended) 40 GB free

The on‑disk footprint can grow with patches and new content, so keeping closer to 40 GB free gives you headroom for updates.

Where to install on PC

You can play on PC via the game’s own launcher, Steam, or Epic. If you prefer the standalone launcher, download it from the official Duet Night Abyss site. If you’re using Steam and meet the Windows 10+ requirement, install from the game’s Steam page mentioned above.

The bottom line: a GTX 1060 or RX 580 with 16 GB of RAM clears the minimum bar; an RTX 2060 or RX 5700 XT with 32 GB of RAM lines you up for higher settings. Set aside at least 32–40 GB on your drive, and make sure your OS meets the Steam client’s Windows 10+ requirement if you’re installing through Steam.
