SCSKiller

Shader Compilation Stutter Killer. SCSKiller compiles your games' shaders into your GPU driver's cache before you play, so the game doesn't stop to compile them mid-game. Free and open source, for Windows.

A game that meets a new effect has the GPU driver compile its shader on the spot, and the frame waits: that's shader compilation stutter. SCSKiller reads the shaders a game ships with, works out the pipelines it will build, and compiles them into the driver's cache ahead of time, in its own process with the game closed.

Can I get banned? SCSKiller only reads the files of games with anti-cheat and adds its recorder to them only in a session you allow and confirm (next question). Its anti-cheat check can still miss a game, so you use SCSKiller at your own risk, and its authors are not responsible for bans, crashes or lost data.

Is it safe with anti-cheat games? Outside a session SCSKiller never launches them, injects into them or gives them the recorder. It only reads their files. A session is allowed per game, confirmed every launch, and at your own risk. The offline session for ELDEN RING and ARMORED CORE VI runs them offline without EasyAntiCheat when their exe is started directly: Steam must be running (offline mode is fine), and SCSKiller adds d3d12.dll, scskiller.ini and steam_appid.txt to the game's folder and starts the exe itself. With "Allow the recorder in games with anti-cheat (at your own risk)" on in Settings, any other supported game can run a session too: SCSKiller starts the game as usual, with d3d12.dll and scskiller.ini in its folder. Games with anti-cheat can treat the recorder as cheating and ban your account, during the session or later. No game is known to be safe. Enabling the recorder in these games is at your own risk, and SCSKiller isn't responsible for bans. Bans from it are not support issues. In both kinds the recorder records only that process. When the game exits, SCSKiller takes those files out again (each only while it is still the file it added) and keeps the recording and the session's frame times, at the next logon or start if SCSKiller was closed or the PC crashed. If those files are still there when you start the game online, you could be banned. Don't uninstall SCSKiller while the game runs.
