What is SCSKiller?
SCSKiller is a free and open-source Windows utility that targets shader compilation stutter in PC games. It scans a game's shaders and pipelines and compiles them into the GPU driver's cache before gameplay begins.
It supports NVIDIA and AMD GPUs for DirectX 12 games, with DirectX 11 support available on NVIDIA. It can also use an optional recorder for games whose required pipelines cannot be fully determined from their files.

Installation, shader cache paths, GPU support, recording, safety, and game-specific notes for SCSKiller.
SCSKiller How It Works
SCSKiller targets shader compilation stutter by preparing shader pipelines before a game needs them during gameplay. Its main workflow is Scan, Plan, and Compile, with the resulting pipelines placed in the GPU driver's shader cache.
SCSKiller Installation Guide
SCSKiller provides both an installer and a portable Windows build. The official project documentation also explains the current code-signing limitation and how users can verify downloaded files.
SCSKiller Cache Paths
SCSKiller writes prepared pipelines into the GPU driver's shader cache. These are the cache locations used for NVIDIA DXCache, NVIDIA GLCache, and AMD DxCache.
%LOCALAPPDATA%\NVIDIA\DXCacheNVIDIA DirectX shader cache folder%LOCALAPPDATA%\NVIDIA\GLCacheNVIDIA OpenGL shader cache folderAMD\DxCacheAMD driver DxCache folder. Do not delete it while the driver is running.SCSKiller System Requirements
SCSKiller currently targets 64-bit Windows PCs using supported NVIDIA or AMD graphics hardware. Graphics API support differs slightly between the two GPU vendors, while Intel GPUs are not currently supported.
SCSKiller Supported Game Stores
SCSKiller can automatically find installed games from a range of major PC launchers and storefronts. Store detection lets the library group games by their source and launch supported titles through their normal store.
SCSKiller Recorder Guide
SCSKiller includes an optional recorder for games whose required pipelines cannot be fully determined from game files alone. The recorder can collect pipeline activity and frame-time information from a play session, after which SCSKiller can use the recording for compilation.
SCSKiller Anti-Cheat Safety
SCSKiller applies special restrictions to games containing anti-cheat systems. Its normal policy is to read those games' files without launching, injecting into, or enabling the recorder for them.
SCSKiller Game Compatibility
SCSKiller game notes cover titles with official sample measurements on https://scskiller.com/ and the documented offline recorder exception. Results vary by game, GPU, and driver.
SCSKiller Support Status
SCSKiller support status groups games from the official sample table on https://scskiller.com/ and from the documented recorder and GPU limits. Results vary by game, GPU, and driver.
Final Fantasy VII Rebirth, Silent Hill: Townfall, and Tiny Tina's Wonderlands are in the official sample table, with cold-cache stalls of at least 20 ms dropping to 0 after compilation.
Hogwarts Legacy is in the same official sample table: 1,014 stalls of at least 20 ms on a cold cache and 87 after compilation. Games whose pipelines cannot be read from files need the optional SCSKiller recorder.
Games on Intel GPUs are outside current SCSKiller support. DirectX 11 games on AMD GPUs are outside current API support.
SCSKiller Free and Supporter Features
The core SCSKiller application is free and open source, and its local compilation and recording features do not require an account. Optional Patreon tiers fund the community database and provide additional community-data or early-build benefits.
