Rehaunted minimum requirements: PC specs and file size

Pulling up the Rehaunted minimum requirements before you hit install saves you from a 20 GB download that refuses to launch, and it tells you whether your laptop can actually run a first-person detective horror game at smooth framerates. Rehaunted launched on Steam for Windows PC on September 14, 2026, and because it is a focused single-house investigation, the hardware bar stays surprisingly low — but the recommended specs, the Rehaunted download size, and the known performance issues still catch first-time players off guard.

This page walks through the exact minimum and recommended spec tiers, breaks down the Rehaunted file size, flags the Rehaunted known issues and bug fixes already shipped in the launch window, and gives you a quick compatibility check before you commit disk space. Everything below is sourced from the official Steam store page, the Cauchemar studio site, and community reports collected on launch day.

Rehaunted Minimum Requirements vs Recommended Specs

The gap between Rehaunted minimum requirements and the Rehaunted recommended specs is narrow because the game renders one house, not an open world. That said, the recommended tier exists for a reason: if you want steady frame pacing during the UV flashlight sweeps and the walkie-talkie dialogue triggers, the higher CPU and RAM floor matters more than raw GPU power. The official store page lists both tiers, and they map cleanly onto hardware from the last six or seven years.

According to the official Rehaunted store page, an SSD is the meaningful upgrade between the two tiers, not the GPU. Loading between chapters is where HDD users hit long stalls, while the actual scene rendering stays well within reach of a GTX 1060. The game's narrow scope also means VRAM matters more than shader count: a 6 GB card on minimum and an 8 GB card on recommended keeps texture swapping invisible during evidence sweeps.

Why 8 GB of RAM Is the Real Floor

Community testing on launch day showed that 8 GB of system RAM works on minimum, but only if you close Chrome and Discord before launching. The Rehaunted process holds roughly 5.2 GB at peak during a UV flashlight pass in a fully lit room, and Windows 10's background services easily push the working set over 7 GB. If you want a clean experience, the 16 GB recommended tier is the safer buy, especially because the Rehaunted file size is small enough that most players will leave it installed permanently.

CPU Choice: Older i5s Still Hold Up

The CPU requirement is forgiving because Rehaunted does not simulate crowds, physics chains, or weather. A 7th-gen i5-7400 runs the title at 1080p 30 FPS without dropping into the high 20s during walkie-talkie dialogue scenes, which is when the script interpreter peaks. If you have a Ryzen 5 1600 or any quad-core with SMT from the same era, you can treat the minimum tier as your baseline without compromise. Pair that information with our deeper Rehaunted settings guide if you want to tune the in-game graphics options after installation.

Rehaunted File Size and Download Details

The Rehaunted download size is one of the friendlier numbers in 2026's horror lineup. The game ships without a day-one patch that doubles the install footprint, and the build is already compressed efficiently on Steam. Most players see a download between 11 and 14 GB before decompression, with the on-disk install landing at the 15 GB mark the system requirements promise.

The Rehaunted file size is small because the entire investigation takes place inside one house with a fixed set of rooms, props, and audio layers. There is no open world to stream, no cinematic campaign with 4K baked-in cutscenes, and no live-service download layer. The bulk of the install is voice acting for the walkie-talkie radio and the high-resolution textures used by the magnifier and camera tools.

Pre-Load, Decompression, and Disk Partition Tips

Pre-load opened on September 13, 2026, which gave Steam users a full day to download the build before the September 14 unlock. Players on mechanical drives reported a 25 to 40 minute decompression phase after the download finished, while SSD users skipped that step entirely. If you are tight on disk space, the recommended move is to install on your fastest drive, even if it is a smaller SSD, because the load times during chapter transitions are the most visible quality-of-life hit in the game.

Language Pack Overhead

The base install already includes the English, French, Spanish, German, and Japanese voice tracks. According to the Rehaunted language options page, the text layer adds another 600 MB of localized subtitles and UI strings on top of the core 15 GB. If you switch audio languages after install, Steam only pulls the extra voice pack on demand, so a single-language install stays around the 15 GB mark for most users.

Rehaunted Performance Issues and What Causes Them

Rehaunted is not a heavy game, but it is sensitive to a handful of specific bottlenecks that show up in the first hour of play. The known Rehaunted performance issues reported on launch day cluster around three areas: long initial shader compile, microstutter during walkie-talkie dialogue, and frame pacing dips in rooms that combine the UV flashlight with a magnifier close-up. None of these are deal-breakers, and the Cauchemar team has been pushing small Rehaunted bug fixes through Steam since launch.

The most common Rehaunted performance issues are actually fixable without a patch. Borderless windowed, a 60 FPS cap, and forcing your audio sample rate to 48 kHz together resolve roughly 80% of the complaints posted to the Steam community hub on day one.

Shader Compile and Why It Looks Like a Crash

The first launch allocates 8 to 12 minutes to a one-time shader compile, depending on your GPU. The launcher shows a progress bar that looks stalled, and a small number of players killed the process during this window, which is why "Rehaunted won't launch" threads appeared within hours of release. The Cauchemar team addressed this in a Sept 15 hotfix that surfaces a clearer "compiling shaders" message, and a Sept 18 patch added an optional pre-compile flag to the launcher so power users can skip the in-game pause entirely.

CPU-Bound Microstutter Explained

Rehaunted uses a single-threaded script interpreter for the walkie-talkie radio dialogue system, and that interpreter spikes when Connor and his partner exchange lines while a room event is firing. On older i5 CPUs the spike lasts 80 to 120 milliseconds, which is enough to feel like a hitch even at a 60 FPS average. Capping your framerate through the in-game settings or via the GPU driver panel smooths the pacing because the cap converts those spikes into a single dropped frame rather than a visible judder.

Rehaunted Known Issues and Bug Fixes Already Shipped

The launch window for Rehaunted has been unusually clean for a first-person horror debut, but the Rehaunted known issues list still includes a handful of small bugs that the community surfaced within the first 72 hours. Most of the items below were flagged on the Steam community hub and then fixed in one of three hotfix patches that shipped between September 14 and September 20, 2026.

The most important Rehaunted bug fixes for completionist players are the post-credits scene fix and the ending flag patch, because both could block progress toward a specific Rehaunted ending choice chain. If you played during the first 48 hours and your save predates the Sept 20 patch, the safest move is to reload an earlier save or let the patch re-validate the ending flag automatically on next chapter transition.

Audio Bugs and Realtek Workarounds

A subset of players on older Realtek audio drivers reported crackling during the walkie-talkie scenes, especially when the dispatcher's voice layered over an in-room ambient track. The fix is a Windows-side setting: open Sound Control Panel, find your output device, go to Properties → Advanced, and force the sample rate to 24-bit, 48000 Hz. This is a driver-level workaround, not a game patch, but it is the single most effective fix for the audio complaints still appearing on the community hub.

Save File Compatibility Across Patches

Saves from launch day remain forward-compatible with the current build, which is good news for anyone who started before the Sept 20 patch. The Cauchemar team confirmed in the Steam developer page for Cauchemar that no save migration is required and that patched flag values are reapplied automatically when the relevant chapter reloads. This means a player who hit the post-credits bug can simply re-enter the final room and the corrected ending will fire without losing earlier progress.

How to Pre-Flight Your PC Before Installing Rehaunted

Before you click install, run a quick hardware check that mirrors what the Rehaunted minimum requirements actually test. The steps below take about five minutes and catch the most common install-time failures, from missing DirectX runtimes to disk space surprises on a crowded boot drive.

1. Confirm Windows 10 64-bit or newer. Open Settings → System → About. Rehaunted will not run on Windows 7 or 8.1 even if the rest of your hardware meets minimum.

2. Check free disk space. You need at least 18 GB free to cover the 15 GB install plus decompression headroom. Use Settings → System → Storage to confirm the boot drive.

3. Verify your GPU driver is current. NVIDIA 552.22 and AMD 24.3.1 or newer both fix the magnifier flickering bug. Older drivers work but show minor visual artifacts.

4. Test your audio sample rate. Right-click the speaker icon → Sounds → Playback device → Properties → Advanced → set 24-bit, 48000 Hz.

5. Close background recorders. OBS, Discord screen share, and Xbox Game Bar add a 3 to 5% CPU tax that pushes minimum-tier systems under 30 FPS.

6. Pre-allocate 30 minutes for first launch. The shader compile step is a one-time cost. Skipping it by killing the process is the most common cause of the "won't launch" threads. If your PC passes this checklist, you will spend more time inside the house than waiting on the install. Players on a GTX 1060 / i5-7400 / 8 GB / HDD combination report a fully playable 1080p 30 FPS experience with only the long chapter transitions feeling slow. Moving to an SSD is the single upgrade that pushes that experience into the recommended tier, even on otherwise minimum hardware. Once you have installed the game, the next sensible step is to read our walkthrough on how to find every document and key in Rehaunted so you know where the evidence layer meets the hardware layer.

Frequently Asked Questions

What are the Rehaunted minimum requirements for PC?

The Rehaunted minimum requirements are Windows 10 64-bit, an Intel Core i5-7400 or AMD Ryzen 5 1600, 8 GB of RAM, and an NVIDIA GTX 1060 6GB or AMD RX 580 8GB. You also need 15 GB of free storage and DirectX 11. An SSD is recommended because HDD users see long chapter-transition stalls even when the rest of the spec matches.

How big is the Rehaunted file size and download size?

The Rehaunted file size is 15 GB on disk, and the Rehaunted download size from Steam is roughly 12 GB before decompression. Pre-load opened on September 13, 2026, so most players let the build download overnight and installed the following day. The install is small for a 2026 horror release because the entire game takes place in a single house.

Does Rehaunted have known performance issues on minimum specs?

Yes, the most common Rehaunted performance issues on minimum hardware are long shader compile on first launch, microstutter during walkie-talkie scenes on older i5 CPUs, and frame pacing dips when the UV flashlight and magnifier are used together. Most of these are fixable through in-game settings, borderless windowed mode, and a 60 FPS cap, and several have already been addressed in the Sept 15 to Sept 20 hotfix patches.

Are there Rehaunted bug fixes I should know about before playing?

The most important Rehaunted bug fixes for new players are the Sept 16 hotfix that removes fullscreen exclusive mode, the Sept 18 patch that fixed the UV flashlight battery counter, and the Sept 20 patch that resolved the post-credits scene trigger. According to the official Rehaunted Steam news page, saves remain forward-compatible across all of these patches, so older playthroughs pick up the fixes automatically.

Can my laptop run Rehaunted if it only meets the recommended GPU but has minimum RAM?

You will see the game launch, but you will hit stutter whenever the walkie-talkie script interpreter spikes. The 8 GB floor is the real bottleneck on minimum, and a memory upgrade to 16 GB will do more for frame pacing than a GPU swap. If you cannot upgrade the RAM, cap your framerate at 30 FPS through the in-game settings and close all browser tabs before launching.
