Undead Labs confirmed State of Decay 3 runs on Unreal Engine 5 with a launch map roughly four times the size of State of Decay 2 — and that's about all the technical detail we have. No PC spec sheet exists yet, so this page is a clearly-labeled projection.

FPS expectations
Estimated, not measured — modelled from PROJECTION — no build exists to benchmark and Undead Labs has not published PC requirements. Anchored to Unreal Engine 5.4+'s typical open-world profile with Lumen GI (the same engine class as Fable on this site), with a downward adjustment for State of Decay 3's persistent zombie-population simulation running continuously across a map roughly 4x State of Decay 2's size — that kind of always-on world simulation tends to tax the CPU harder than a scripted open world does. Undead Labs is working with The Coalition (Gears of War Reloaded's UE5 team) on the engine work, which is a positive optimization signal but not a substitute for a real spec sheet. Treat as directional; will be rebuilt entirely once one exists.. How we estimate FPS.
Recommended builds
1080p Budget (Projected)
Projected 1080p high settings — a conservative starting point until Undead Labs publishes real requirements.
1440p Sweet Spot (Projected)
Projected 1440p target build, weighted toward CPU cache given the always-on world simulation this series is known for.
4K Ultra (Projected)
The most speculative tier on this page by construction — revisit before buying once real specs land.

What we actually know: engine and scale, not requirements
State of Decay 3 got its first real gameplay reveal at the Xbox Games Showcase in June 2026, confirming Unreal Engine 5 and a launch map about four times the size of State of Decay 2 — with The Coalition, the studio behind the Unreal Engine 5 rebuild of Gears of War, assisting on the engine side. That's a meaningful technical signal, but it is not a spec sheet, and Undead Labs hasn't published one.
The Steam store page exists and is open for wishlisting, but its listed PC requirements are still the generic Windows 10 placeholder text every unreleased Steam page ships with by default — not real numbers. We're not going to dress that up as official data.
Why we expect this to lean CPU-heavy
The State of Decay series has always simulated its zombie population and survivor AI continuously, even off-screen — that's the genre's whole hook. A map four times larger than its predecessor's, built to keep that simulation running persistently, points toward a CPU-bound profile more than a pure GPU one, similar to how DCS World or Baldur's Gate 3's Act 3 behave on this site. We'll confirm or correct this the moment real specs or benchmarks exist.
Frequently asked questions
Has Undead Labs published State of Decay 3 system requirements?
No. The Steam page exists but still shows placeholder requirements text. Everything on this page beyond the confirmed Unreal Engine 5 engine and map-scale detail is a projection, clearly labeled as such.
When does State of Decay 3 release?
Undead Labs has confirmed a 2027 window (reports point to February 2027) for PC, PlayStation 5, and Xbox Series X|S, with Xbox Play Anywhere and Game Pass support. An exact date hasn't been announced.
Is State of Decay 3 CPU-bound or GPU-bound?
Unknown for certain until real benchmarks exist, but we'd bet CPU-bound — the series has always run a persistent, always-on zombie and survivor simulation, and this entry's map is roughly 4x larger than State of Decay 2's.
