Ah, much faster! Is there a way to show ribbons without having it recompute the shape at every step? Is this something a more powerful computer could handle? I'm not driving a Rolls Royce yet, but maybe one day.

Ok, next thought is if you are showing ribbons it has to recompute the ribbon shape every time step and that takes some time. How fast is it in sphere display style?

Hi Chad, The problem is probably you are using "soft" or "full" lighting which computes ambient shadows from 64 directiions each time the shape of the protein changes. That is done on the graphics card and is time consuming. Switch to simple ZjQcmQRYFpfptBannerStart This Message Is From an External Sender This message came from outside your organization.

When I look at my Windows taskmanager, I can see that neither my CPU (12th Gen Intel i7-12700H), RAM, or GPU (NVIDIA RTX 3050 Laptop) are maxed out. Is there a way to speed up Chimera morphs?
