Ray Tracing and Path Tracing Real Time Toggle

Ray Tracing, Path Tracing, Hairworks and Frame Gen Real Time Toggle

Switch Hairworks (Off / Geralt / All), Ray Tracing and Path Tracing (Off / RT / RT+PT) and Frame Generation (Off / On) in real time with a single key for each, without opening the options menu. A short notification shows the new mode, and each change is saved just like in the options menu.

Suggested usage: play with these graphics features on and switch them off when engaging in combat to improve performance and reduce input lag.

Requirements: The Witcher 3 Next Gen.

Installation: extract into the game folder, or install with Vortex. Then, with the game closed, add the hotkeys to Documents\The Witcher 3\input.settings: run the optional Key installer (Files tab), or add the lines by hand (listed in the README).

Options: Options > Mods > RT Toggle (on/off and the key for each function; default F7 / F8 / F9).

About the Key installer

The game reads hotkeys from input.settings, and a script mod can't add keys there by itself. The Key installer, in the optional files, does it for you. It's plain text: right-click install-keys.bat or keys.ps1 > Edit (or open them in Notepad) to read every line before running it.

• []It only changes input.settings, and backs it up first (input.settings.modRTtoggle.bak).[/]

  []No admin rights, no internet, no downloads, no registry or Windows settings changes. "-ExecutionPolicy Bypass" applies to that single run only.[/]

  []It won't run while the game is open, and running it twice doesn't duplicate anything.[/]

  []remove-keys.bat undoes it.[/]

Don't want to run it? Add the 17 lines by hand: the README in the main file lists them and where they go.

AI disclosure

The code of this mod was written with Claude Opus 5. 5 and tested in-game by me. It only changes the game's own graphics settings.
