Proton/Wine NVIDIA Highlights -> gpu-screen-recorder bridge

This repo contains:

• sourcecode for a mocked GfeSDK.dll shim for Wine/Proton that reports NVIDIA Highlights via UDP
• a Linux UDP listener that receives highlight events and runs a replay-save command.

Files

• gfe_shim/GfeSDK.c: Windows DLL shim source.
• gfe_shim/GfeSDK.def: exported symbols.
• gfe_shim/Makefile: build helper.
• bridge/highlight_listener.sh: Linux event listener.

1) Build the mock DLL

Install MinGW cross compiler first (package name depends on distro).

Debian: sudo apt-get install gcc-mingw-w64-x86-64 g++-mingw-w64-x86-64 wine64

Build:

cd gfe_shim
make

Output:

• build/GfeSDK.dll

2) Put the mocked dll where the game loads GfeSDK.dll

Copy build/GfeSDK.dll to the game directory and replace existing file.

Then adjust Steam launch options and replace with Linux User Home Directory :

GFE_SHIM_SEND_UDP=1 GFE_SHIM_LOG_FILE="Z:\\home\\<user>\\gfe_shim.log" %command%

3) Start gpu-screen-recorder

The following assumes you installed gpu-screen-recorder via flatpak Adjust Parameters to your format and output folder

flatpak run --command=gpu-screen-recorder com.dec05eba.gpu_screen_recorder -w DP-1 -f 60 -a "default_output" -c mkv -r 60 -o /home/<user>/Videos

4) Start Linux listener

The listener receives UDP messages on 127.0.0.1:31337. Default action is for saving replays

highlight_listener.sh

Env variables can be set to overwrite, delay (HIGHLIGHT_ASYNC_DELAY_SEC), save Signal to gpu-screen-recorder (GSR_SAVE_CMD)

Notes

• Tested with MK11, Uncharted Legacy of Thieves, Shadow of the Tomb Raider under Debian 13 with GE_Proton
• This is a proof-of-concept no finished work.
• Some anti-cheat systems may treat this as tampering. Avoid for protected online play.
