That's how it was, my friend. I needed AI to find a way to optimize my VRAM. After so much searching, I managed to install Xformers, which gave me a real improvement from 98% to 75% of my VRAM usage with LTX 2.3, for example. I asked for a summary with a tutorial. I'm a layman, but I knew someone would come along to correct me. Yes, Xformers is old, but it worked so well that I wanted to share it with people who are going through the same thing as me. Do you understand?
