Human Farm Investigation System Requirements

Overview

Human Farm : Investigation : (Steam app 3953160) is an RPG Maker–style story RPG from developer とっくり海月 and publisher 072 Project, released on August 7, 2026. Requirements are modest by modern PC standards, but you should budget extra disk space if you plan to install the free official patch RP26071196 alongside the base Steam depot.

This page summarizes Steam store minimum and recommended specs, patch footprint, and practical setup advice for players coming from the Day 1 demo (app 4629570) or older Human Farm series entries.

Minimum requirements (Steam)

Per the Steam store listing for app 3953160:

Component	Minimum
OS	Windows 10 or later (64-bit)
Processor	Intel Core i3 or equivalent
Memory	4 GB RAM
Graphics	DirectX 9 compatible GPU
DirectX	Version 9.0c
Storage	4 GB available space
Additional	Keyboard required for doors and menus

The game runs in windowed or fullscreen modes typical of RPG Maker titles. Mouse is supported for menus but does not open doors on the Steam build — plan on arrow keys plus Z or Enter — see Keyboard Controls.

Recommended requirements

Steam lists a slightly higher bar for comfortable play:

Component	Recommended
OS	Windows 11 (64-bit)
Processor	Intel Core i5 or equivalent
Memory	4 GB RAM (same floor as minimum)
Graphics	NVIDIA GeForce GTX 650 or AMD Radeon RX 460 class or better
DirectX	Version 9.0c
Storage	4 GB for base game; see patch section below

Recommended specs mainly help map transitions and fullscreen scaling on 1080p displays. Investigation is not a 3D action title — integrated GPUs often suffice if they meet DirectX 9 support.

Storage: base game vs patch RP26071196

The base Steam install targets roughly 4 GB on disk. The official restore and bugfix patch RP26071196 from 072 Project adds approximately 500 MB when extracted and copied into the game folder.

Important patch notes affecting storage planning:

• Patch cannot run alone — you need the full Steam game installed first.
• Installation is folder copy and overwrite, not a standalone installer — see Official Patch and Patch Install Helper.
• Keep a backup copy of the patch archive and optionally duplicate the game folder before overwriting — rollback avoids redownloading ~4.5 GB combined.

After patching, Steam Verify integrity of game files may revert modified assets. Reapply RP26071196 if verification restores the default Steam cut.

Operating system guidance

Windows 10 meets minimum. Windows 11 is recommended in store text and aligns with publisher testing for the August 2026 launch window.

Linux and macOS are not listed as supported platforms on Steam for this title. Proton or Wine may work unofficially but are outside wiki scope — expect keyboard and fullscreen quirks.

Hardware quality-of-life

Even when specs pass, these habits improve play:

• Install on SSD if available — RPG Maker map loads stutter on slow HDDs during farm-to-city transitions.
• Enable run mode in the options menu immediately — Settings and Run Mode — to reduce real-time lost crossing large maps.
• Close background capture tools if frame pacing feels uneven; the engine is lightweight but sensitive to overlay hooks.

Demo vs full game requirements

The free demo (app 4629570) covers Day 1 only and uses a separate depot. Specs match the full game, but demo saves do not carry over. Do not apply RP26071196 to a demo-only install — patch targets the paid app 3953160 folder — Demo Day 1.

Patch-specific requirements

RP26071196 is distributed as a compressed archive from 072 Project regional shop pages (for example the CN host path documented on Official Patch). You need:

• Administrator rights to paste into the Steam library folder (Gear → Manage → Browse local files)
• Free space for extraction temp files (~500 MB archive plus extracted folders)
• Ability to overwrite existing game assets when Windows prompts

Antivirus may flag mass file overwrites — whitelist the game directory during install if needed — Common Issues.

Display and input

• Resolution: follow in-game options; 1920×1080 fullscreen is common on recommended GPUs.
• Text languages: English, Japanese, Simplified Chinese, Traditional Chinese on Steam — language choice does not change hardware demand.
• Controller: not required; keyboard-first design matches series entries — Series Comparison.

Checking your build

After launch, note your Steam build ID (Library → Properties → Updates) when comparing requirements discussions or patch changelogs — Version History tracks RP26071196 and the recall-room warning text update from 26/08/07.

Meeting minimum specs gets you in the door; recommended specs plus SSD and run mode make calendar-heavy investigation days far less frustrating.

Upgrade path for series veterans

Players who ran Rehabilitation or Practice Section on older laptops should expect similar engine load. Investigation adds city maps but not heavier 3D assets — if those titles ran, Investigation likely will too after enabling run mode.

Pre-purchase checklist

Before buying during the Steam introductory offer window, confirm 64-bit Windows, 4 GB RAM free, DirectX 9 GPU, and at least 5 GB disk if you intend to patch immediately after install.
