What hardware does the official announcement list?

The October 5 announcement specifies two PC targets. Compare each component rather than using only the GPU model to infer performance. A requirement is the developer’s stated target, and does not establish frame pacing, performance on every driver, or compatibility with an operating system not listed.

Component Minimum: 720p / 30 FPS Recommended: 1080p / 60 FPS
OS Windows 10, 64-bit Windows 11, 64-bit
CPU Intel Core i5-7400 / AMD Ryzen 5 1600 Intel Core i5-9600K / AMD Ryzen 5 3600
RAM 8 GB 12 GB
GPU GeForce GTX 1060 3 GB / Radeon RX 580 4 GB GeForce RTX 2060 Super / Radeon RX 5700 or better
DirectX 11 12
Available storage 10 GB 15 GB
Drive note SSD strongly recommended SSD strongly recommended

How much disk space should I reserve?

Use the applicable available-space figure above and check Steam’s installation estimate before downloading. The announcement’s 10 GB and 15 GB are storage requirements, not measurements of compressed download size. Updates or temporary installation files can require more free space than the final game folder.

Is Steam Deck or Linux compatibility confirmed here?

No. We have not independently tested Steam Deck, Proton or Linux. The Windows requirements cannot prove handheld compatibility. Likewise, this page does not provide an invented best-settings preset, a 4K target or benchmark results.

For a performance report, include your CPU, GPU, RAM, storage, resolution and settings, and explain where the issue occurs. Getting started includes feedback guidance; playtest access links the official channels.

Will full-release requirements be identical?

We cannot establish that yet. Recheck the store when the full game releases and compare it with the current release window. This page preserves the scope of the October announcement rather than treating a prerelease target as a permanent guarantee.
