TotK PC Recomp Requirements: Hardware and Software Guide

Overview

The TotK PC Recomp project (`valentderah/totk-pc-recomp`) provides a static recompilation of *The Legend of Zelda: Tears of the Kingdom* that runs as native x86-64 Windows code using a Vulkan renderer. As of October 30, 2026, the project is in beta. To run the application, your PC must meet specific hardware and software thresholds. TotK Recomp requires Windows 10 or newer, a CPU with AVX2 support, a GPU supporting Vulkan 1.3 with the `VK_EXT_external_memory_host` extension and at least 4 GB of VRAM, 16 GB of system RAM, and approximately 36 GiB of free disk space for setup.

TotK PC Recomp Hardware and Software Requirements

The following specifications are required to run TotK Recomp. These thresholds ensure the static recompilation can execute native code and interface correctly with the Vulkan renderer.

* **Operating System:** Windows 10 or newer. * **Processor:** A CPU with AVX2 instruction set support is mandatory. * **Graphics:** A GPU compatible with Vulkan 1.3. The graphics driver must support the `VK_EXT_external_memory_host` extension. A minimum of 4 GB of VRAM is required. * **Memory:** 16 GB of system RAM. * **Storage:** Approximately 36 GiB of free disk space is needed during the initial setup process. After setup, the installation size reduces to about 20 GiB.

Setup, Storage, and Game Files

Storage management is critical during installation. The setup process requires roughly 36 GiB of free space to handle temporary files and recompilation data. Once the process completes, the disk footprint drops to approximately 20 GiB. Ensure your drive has sufficient headroom before starting to avoid setup failures.

TotK Recomp does not include any game files. You must provide a legally obtained copy of the base game plus either the 1.2.1 or 1.4.3 update. The project explicitly asks users not to share the recompilation tool, emphasizing that it is intended for personal use with owned game data.

Beta Status and Stability

The first public release, version 0.1.1, was distributed on October 29, 2026. This build is labeled beta. Players should expect crashes and visual bugs during gameplay. The project is actively refining the codebase, and stability is not yet guaranteed. Users are encouraged to back up save data and report issues to the developers to assist with future updates.

Understanding Static Recompilation

TotK Recomp uses a static recompilation approach rather than emulation. Emulators imitate Switch hardware in real time, which can introduce overhead. Static recompilation translates the game's original machine code into native x86-64 instructions that run directly on the PC processor. This method produces a native Windows application with a Vulkan renderer, potentially offering performance advantages over emulation layers. However, the translation process is complex, and the beta nature of the current release means some game systems may still require optimization.

TotK Recomp vs. SkyboundTOTK

Players searching for native PC options may encounter two distinct projects. TotK Recomp (`valentderah/totk-pc-recomp`) is the static recompilation detailed in this guide. A separate project, SkyboundTOTK, is an unofficial native PC port developed by modder NotRexed. SkyboundTOTK also recompiles the game's machine code to run directly on PC processors without emulation.

While both projects aim for native performance, they are independent efforts with different feature sets and development stages. SkyboundTOTK is currently a dev or beta release with known bugs. Early builds of SkyboundTOTK demonstrated frame rates between 32 and 59 FPS on a GeForce RTX 4060 Ti, though the developer noted the game felt sluggish at that stage.

SkyboundTOTK includes several features that may interest PC players: * **FSR Upscaling:** Support for FidelityFX Super Resolution upscaling. * **Frame Interpolation:** Experimental frame interpolation to smooth motion. This inserts frames between rendered ones but does not increase the game simulation rate. It may introduce input latency and visual artifacts, particularly during fast movement or menu navigation. * **Ultrawide Mode:** An experimental ultrawide mode adjusts the field of view and HUD for wider displays, though it may stretch the image on some configurations. * **Display Options:** Users can choose between fullscreen and windowed modes. Options exist to preserve the original aspect ratio or stretch the image to fill the screen. Display preferences can be saved for subsequent sessions. * **Local Cache:** A local graphics cache improves performance in later sessions, though it may not eliminate all stuttering during shader compilation or scene loading.

For Mac users, a separate recompilation project targeting Apple Silicon has reportedly reached 90 FPS during gameplay, outpacing early PC builds and the official Switch 2 Edition.
