Sometimes—but only shader-compilation stutters that SCSKiller can identify and prepare. The free Windows tool compiles some game pipelines into the graphics-driver cache before you play. Its developer reports large reductions in recorded shader stalls in several RTX 5090 game tests, but those results are not independent benchmarks, and the tool does not fix every kind of hitch.
What SCSKiller does
When a game encounters a graphics effect whose shader or pipeline is not ready in the driver cache, it may need to compile it during play. If the game waits for that work, the pause can appear as a hitch. SCSKiller reads shaders shipped with a game, identifies pipelines it can build, and compiles them into the GPU driver’s cache while the game is closed. The project describes its purpose as preparing shaders before play so the game does not stop to compile them mid-game. SCSKiller project documentation

GeForce compatibility and requirements
The project lists 64-bit Windows 10 version 2004 or Windows 11, and support for NVIDIA and AMD graphics. For GeForce users, it lists DirectX 12 games and DirectX 11 games; Intel GPUs are not supported yet. Compatibility is game- and API-specific, so check the project’s current information for your game and setup before relying on it. SCSKiller compatibility information

What the RTX 5090 results show
The SCSKiller project reports tests of about five minutes of play per game: first with a cold driver cache, then after compiling with SCSKiller. In its table, a qualifying “stutter” is a shader compile the game waited at least 20 milliseconds for. The numbers below are the project’s own recorder measurements on an NVIDIA RTX 5090; they are not independently verified or a guarantee for other GPUs, drivers, game versions, or sessions. The page does not state the table’s publication year. SCSKiller project measurements
| Game | Recorded shader stalls of at least 20 ms: cold cache → after SCSKiller | Worst recorded stall: cold cache → after SCSKiller |
|---|---|---|
| Final Fantasy VII Rebirth | 19 → 0 | 76 ms → 5 ms |
| Silent Hill: Townfall | 24 → 0 | 347 ms → 8 ms |
| Hogwarts Legacy | 1,014 → 87 | 2,400 ms → 100 ms |
| Tiny Tina’s Wonderlands | 583 → 0 | 315 ms → 13 ms |
| Star Wars Jedi: Survivor | 9,038 → 11 | Not stated in the project’s table |
These results suggest the tool can substantially reduce recorded shader waits in the tested cases. They do not establish a general success rate: the project’s table covers particular games and test sessions, and the available evidence does not include an independent controlled benchmark.

What SCSKiller cannot eliminate
The project says the tool targets shader-compilation stutter. It does not address traversal stutter, asset-streaming stutter, or hitches with other causes. Nor can it prepare every shader: anything it cannot identify or record may still compile during gameplay. So “eliminate” applies only to measured shader stalls in some cases, not all stutter in a game. SCSKiller project overview

Download and first-run considerations
SCSKiller is described by its project as free and open source, with downloads available from the official GitHub releases page. The project warns that releases are not code-signed yet, so Windows may display a SmartScreen warning the first time you run one. It recommends checking the SHA-256 value published for the release. Signing and release details can change, so use the live project pages for the version-specific information rather than relying on an old hash or version number.
