The Linux package runs the Windows app under Proton, the compatibility layer known from Steam. A launcher sets everything up by itself. There is no native Linux build, because the DLSS 5 runtime exists only for Windows.

What you need

64-bit Linux with a desktop session (X11 or Wayland).
An NVIDIA GeForce RTX card (20, 30, 40 or 50 series) with the NVIDIA driver 5xx or newer. Radeon cards are not supported on Linux.
python3 (3.10 or newer) and curl or wget.
About 3 GB of disk space for Proton on the first start. Steam is not needed.

Install and start

Download VRChatDLSS5Cam-linux-x86_64.tar.gz from the download section.
Unpack it and start the launcher:
```
tar xzf VRChatDLSS5Cam-linux-x86_64.tar.gz
cd VRChatDLSS5Cam
./vrchat-dlss5-cam
```
The first start downloads Proton, which takes a few minutes. Then the window opens.
Optional: ./install-linux.sh adds the app to your application menu and a vrchat-dlss5-cam command. ./install-linux.sh --remove takes both out again.

Settings, presets, the log and the library live in ~/.local/share/VRChatDLSS5Cam/data. Updates work as on Windows.

What works

	Under Proton
Pictures: DLSS 5, depth, super resolution, presets, undo	Works.
Videos and animated images as input	Works.
Video output	WebP, GIF, APNG or PNG sequence. No MP4, and no sound: Proton has no H.264 or HEVC encoder. A video that would come back as MP4 is saved as WebP.
Live camera (Spout)	Not available. Spout exists only on Windows.
Motion vectors	The FSR optical flow; NVIDIA Optical Flow is not available under Proton.
MCP, updates, mirror sites, languages	Work.
AI Q&A	Ask AI opens it in your browser instead of a panel in the app. AI Q&A
Radeon edition	Not supported.

Command line

The launcher takes the app's options and turns Linux paths into the form the app expects:

./vrchat-dlss5-cam --headless --add ~/Pictures/shot.png --process ~/Pictures/out
./vrchat-dlss5-cam --open ./clip.mp4 --lang zh

--linux-info prints the folders and versions in use, --linux-reset rebuilds the Proton setup (settings and library are kept). All options

If something goes wrong

The first start takes minutes. That is the one-time download of Proton and its runtime, about 2.5 GB.
The window opens but does not react. A locked screen or a screen locker holds the display. Unlock the session.
The picture area shows only a grey checkerboard. The app runs with Proton's own shader compiler. Use the Linux package rather than the Windows zip; it brings the right one.
DLSS 5 stays Inactive. The NVIDIA driver's bridge for Windows programs is missing. ./vrchat-dlss5-cam --linux-info shows whether nvngx.dll was found. Install the NVIDIA driver 5xx or newer.
