Official Steam PC specs · demo vs. full release
Akatori System Requirements
Minimum and recommended PC specs for the full Akatori release, plus the earlier Chapter One prologue demo, straight from each Steam store listing. Pick an edition below, then toggle to see minimum and recommended side by side.
How the two editions compare
The jump between Chapter One's 2024 minimum spec and the 2026 full release's minimum spec is smaller than the four-year gap between them might suggest, but it moves in an unusual direction: the full release actually asks for less memory at the minimum tier (6 GB versus the prologue's 8 GB) while raising the processor bar from a 4th-generation Intel Core i5 to a Core i3-6100, and it drops the OS floor from Windows 7 up to a specific Windows 10 build (21H1, build 19043 or newer). Storage tells a more straightforward story: the full release's 10 GB footprint is five times the prologue demo's 2 GB, reflecting five finished locations, 20+ enemy types, and a full soundtrack compared with the demo's two sample biomes and eight enemy types.
On the graphics side, the full release's minimum GPU — an NVIDIA GeForce GT 740 with 2 GB of VRAM — is a notably older, lower-end card than the Chapter One demo's minimum GTX 750, even though the full game is the larger, more complete product. That's a reminder that "minimum requirements" describe what a game can technically run on, not what it recommends, and Akatori's recommended tier (a GeForce GTX 1050 or Radeon R9 380, both with 2 GB VRAM, paired with an Intel Core i5-3470 and 8 GB RAM) is a more realistic target for the game's full visual effects and enemy density at once. Recommended specs for both editions ask for roughly double the minimum tier's RAM, which tracks with Akatori's five-location full release needing more assets loaded simultaneously than the two-biome demo.
Both editions are Windows-only on Steam; there is no officially listed macOS or SteamOS-specific spec sheet, though a post-launch patch did address Linux-specific display-mode switching and a menu confirmation-window issue, which implies at least some Linux/Proton compatibility work is ongoing even without a dedicated native build. Specs above were captured from Steam's Store API for both appid 1442520 (full release) and appid 2524680 (Chapter One) on .
Reading the processor and memory jump
The recommended-tier processors tell a more consistent story than the minimum tier does: Chapter One's recommended chip is an 8th-generation Intel Core i5, while the full release's recommended chip is a Core i5-3470 — an older-generation part on paper, but one that's still a meaningful step up from either edition's minimum-tier processor. Read together with the RAM figures, the pattern across both editions is the same: recommended specs roughly double minimum-tier memory (8 GB to 16 GB for Chapter One, 6 GB to 8 GB for the full release) while asking for a materially better GPU, which is the standard shape of a "minimum runs it, recommended runs it well" spec sheet rather than two unrelated configurations.
Storage is the one figure where edition size, not hardware generation, drives the difference: Chapter One's 2 GB footprint reflects a two-biome demo, while the full release's 10 GB covers five finished locations, a full roster of 20+ enemy types, and Akatori's adaptive soundtrack. Neither Steam listing specifies solid-state storage as a requirement, but a 10 GB installation with real-time biome loading is the kind of profile that tends to benefit from an SSD even when the store page doesn't say so directly. If you're upgrading a PC specifically to play Akatori, prioritizing the recommended-tier GPU and RAM figures above will do more for a smooth experience than chasing the newest possible CPU generation.
