For CPU mode, download the “portable” version, extract the folders and look for run_cpu.bat.
CPU mode is slow. Some low resolution generations came out in about an hour for 5 seconds, but that’s on a fast desktop. It uses about half the memory and half the CPU time, so I can leave it running in the background without affecting my work too much. Some models take much longer than others.
I’m hoping they get the AMD GPU sorted.
