Keeps NVIDIA Instant Replay always on for the new NVIDIA App (replaces the old GeForce Experience).
Injects a hook DLL into nvcontainer.exe to patch the checks that disable Instant Replay.
This tool exists for one reason — never missing a good clip. We do not condone piracy, DRM bypass, or recording of any protected media; use it responsibly and only for capturing your own gameplay.
hook.dll is injected into the nvcontainer.exe (SPUser instance) and applies three patches:
GetWindowDisplayAffinityhook — always returnsWDA_NONE, preventing overlay detection from disabling recording.Module32FirstWhook — always returnsFALSE, hiding process enumeration used to detect conflicting software.nvd3dumx.dllbyte patch — patches the Widevine L1 capability flag check that disables Instant Replay on protected content.

Run IRPatcher.exe as Administrator.
| Button | Effect |
|---|---|
| Apply Now | Injects the patch for this session only — resets on reboot |
| Remove | Ejects the patch from memory |
| Install | Injects now and registers a scheduled task to auto-apply on every login |
| Uninstall | Removes the patch from memory and deletes the startup task |
Requirements:
- Visual Studio with MSVC (x64)
- Microsoft Detours — clone into a
Detours/folder next to the source files and build it
git clone https://github.com/microsoft/detours Detours
cd Detours && nmake
cd ..
Then open a Visual Studio x64 Developer Command Prompt (as Administrator) and run:
build.bat
This produces IRPatcher.exe.
- furyzenblade/ShadowPlay_Patcher — for the binaries
- womblee/instant_replay_patcher — for the binaries
- Instant Replay must be turned on and actively recording before applying the patch. The patch targets the process that runs while recording is active — if Instant Replay is off or not yet running, the injection will have nothing to hook.
- Tested on Windows 11 with NVIDIA App.
- The patch is applied in-memory and does not modify any files on disk.
- The scheduled task runs the patcher at login with highest privileges so the injection works without a UAC prompt each time.
