TotK Recomp system requirements
You need a reasonably modern PC and your own game files. Here is everything the setup checks before it starts.
PC requirements
| Part | Requirement | Notes |
|---|---|---|
| OS | Windows 10 or later; Linux 6.7+ with glibc 2.34+ | Linux AppImage is new in 0.2.1 and barely tested |
| CPU | x86-64 with AVX2 | Intel Haswell (4th gen) or newer, AMD Ryzen or newer |
| GPU | Vulkan 1.3 with VK_EXT_external_memory_host | Current driver. 4 GB VRAM listed in the 0.1.1 notes |
| RAM | 16 GB | From the 0.1.1 release notes |
| Disk | About 36 GB free during setup, 20 GB after | The peak comes from extracting the game next to the merged RomFS |
| Mac / Android / ARM | Not supported | See MacNativeGames for Apple Silicon |
Game files you need
- Tears of the Kingdom base game (1.0.0), XCI or NSP
- Update 1.2.1 or 1.4.3, NSP
prod.keysfrom the same console, new enough for that update
All three must come from your own console and your own copy. The setup checks the update by hash, so other versions are rejected. This site does not explain how to obtain any of these files.
Graphics cards: what is known
The developer tests on an AMD RX 9070. Reports from other cards, from the release notes and the known-issues list:
| GPU family | Status (as of 0.2.1) |
|---|---|
| NVIDIA RTX | Generally works; use a current driver |
| AMD RX 7000 / 9000 | Main development target |
| AMD RX 5000 / 6000 | 0.2.1 fixed garbage above 1080p and black characters; if it closes after the Nintendo logo, set astc = cpu |
| AMD RX 470 / 480 / 570 / 580 | Known issue: black world, broken textures or green flashes, no workaround yet (#67) |
| AMD Vega | 0.2.1 fixed missing 3D BC textures |
| Intel Arc / Iris Xe | Runs; reports of flickering and lines are open |
| 4 GB cards | Use astc_bc = 1 and a lower game resolution |

FAQ
Does TotK Recomp work without AVX2?
No. The port needs AVX2: Intel 4th generation (Haswell) or newer, or AMD Ryzen or newer. Older CPUs such as Sandy Bridge and Ivy Bridge are not supported (issue #11).
What is VK_EXT_external_memory_host?
A Vulkan extension that lets the GPU use memory the game allocated. TotK Recomp requires it. Current desktop drivers from NVIDIA, AMD and Intel have it; many Android/mobile Vulkan drivers do not, which is why Android is not supported.
Will it run on a 4 GB graphics card?
The 0.1.1 notes list 4 GB of VRAM. On 4 GB cards, version 0.1.9 added the astc_bc option (Advanced tab), which stores textures in a quarter of the memory at slightly blockier quality, and 0.1.6 fixed slowdowns to about 16 fps when video memory filled up.
Does TotK Recomp run on Mac?
No, TotK Recomp targets Windows and Linux on x86-64. For Apple Silicon Macs there is a separate project, MacNativeGames, which also builds Tears of the Kingdom natively.
