Configure hardware acceleration in FaceFusion

AIVideoMirai·Dec 2025

Demo summary

The guide demonstrates how to navigate the FaceFusion interface and select CUDA under execution providers to utilize Nvidia GPUs for faster processing.

Step-by-step

Locate the left column of the interface containing system settings
Find the Execution Providers section
Select CUDA from the list of providers
Upload the source face and target video in the center column
Click the green Start button

Options

Leave the execution provider on CPU

Watch out for

You must have an Nvidia graphics card to use the CUDA setting
Leaving the setting on CPU will result in painfully slow processing speeds

Tips

Think of the interface in three columns: system settings on the left, media input in the center, and AI fine-tuning on the right
Selecting CUDA is the most important setting for beginners to save hours of processing time

Highlights

“I'm talking hours saved with this one click.”
