Underkeep System Requirements (2026)
The published PC requirement is short: a 64-bit processor and operating system, plus a graphics chip that can run OpenGL 3.2. CPU model, memory, and disk size are not on either store.

Why two Windows floors
Steam still prints Windows 7 / 8 / 10. GOG prints Windows 10 or higher. Steam’s own client note, shown on the store page, says the Steam client itself has required Windows 10 or later since 1 January 2024. I am keeping both rows. Collapsing them into “Windows 10” would hide the disagreement.
Deck
There is no Steam Deck compatibility object on the store details, and the tuxDB page for app 2411200 has no report. “Verified” would be a fabrication. Install size is the same kind of hole: if the page does not print gigabytes, this page does not invent them.
Questions
Can I run Underkeep on Windows 7?
Steam’s minimum line includes Windows 7 64-bit. GOG says Windows 10 or higher. The Steam client itself has required Windows 10 since the start of 2024.
How much RAM does it need?
Not published. Neither store prints a memory figure.
Is it Steam Deck verified?
No rating has been published. Do not read silence as Verified or as Unsupported.
