Copied from the official Steam requirements
Quick answer

For Windows, the official minimum is Windows 11, a dual-core 2.4 GHz processor, 8 GB RAM, Radeon RX 6500 XT or Nvidia 1660 graphics, 1 GB storage, and Vulkan support. Linux has a lighter listed minimum of Ubuntu 12.04 LTS, Intel Core i3, 4 GB RAM, a relatively modern graphics card, 1 GB storage, and Vulkan.

03 / BEFORE BUYING

QUICK PC CHECK

  1. Check your operating system.
    The Windows minimum specifically says Windows 11, not Windows 10.
  2. Compare the GPU model first.
    The RX 6500 XT / Nvidia 1660 line is more informative than storage size when deciding whether an older PC is suitable.
  3. Confirm Vulkan support and current drivers.
    Vulkan is an explicit requirement on both operating-system listings.
  4. Leave more than exactly 1 GB free.
    The download may need temporary space for installation and later updates even though the listed game storage is 1 GB.
  5. Check every machine in the multiplayer group.
    The session experience depends on the weakest player's ability to launch and run the game reliably.

04 / HANDHELD

STEAM DECK STATUS

Current Steam app metadata marks Machine Party as Steam Deck Verified and says the default graphics configuration performs well. The same metadata notes that an external Bluetooth or USB controller may require manual activation through the Steam Deck Quick Access Menu.

Interpretation

“Verified” is useful compatibility evidence, but it is not a promise that every update or peripheral setup will behave identically. Recheck the Steam page after major patches.
