You're right that the shaders run on the GPU, but the process of converting to a gif is mostly using CPU, and just not very efficient overall, so it's not going to be that fast.
Thanks for the reply! about that, you maybe tried record the viewport? I search and found an Addon that does that, I will to try it tomorrow
What Addon is this, I could find that useful as well.
I already take frames directly from the viewport. But if you find an addon that can construct gifs very fast I am interested.
