How to Use

1. Download and Place the Script: Download the installer script from the link above. Place the .cmd file directly inside your main ComfyUI_windows_portable folder. This is the same folder that contains the ComfyUI, python_embeded, and update sub-folders.
2. Run the Installer: Right-click the downloaded script and select "Run as administrator". A command window will open and begin the installation process for Triton.
3. Modify the Startup Script: Navigate to the run_nvidia_gpu.bat file. Right-click on it, select "Show more options" (on Windows 11), and then click "Edit". A notepad window will open.
4. Add Startup Arguments to Enable: At the end of the line that starts with .\python_embeded\python.exe..., add the arguments --fast --use-sage-attention. The final two lines of your file should look exactly like this:

   .\python_embeded\python.exe -s ComfyUI\main.py --windows-standalone-build --fast --use-sage-attention
   pause

5. Ready to Go: Save and close the notepad file. You can now run run_nvidia_gpu.bat normally. ComfyUI will launch with Sage Attention and Triton enabled.
