The place to discuss Faceswap and Deepfakes
https://forum.faceswap.dev/
I know faceswapping is resource intensive, but is there a way to work on say the manual tool while converting? Maybe conversion can use the GPU, while manual tool could use the CPU.
Unfortunately the manual tool needs the GPU for alignment. It is too unresponsive without it....
You could try setting "allow-growth" in the config option prior to converting (would need to launch convert first) and then launch the manual tool, but I don't know if that will work or not.
