ive got some animated proxies in my scene, and they kill the framerate when animating, ( 1 frame every few seconds instead of buttery smooth)
in this case (and many i can think of) it would be good to have a checkbox “only animate at rendertime” so we get static meshes for viewport performance..
its the latest 3.6.. model is quite low poly, but i have “show whole mesh” ticked, and then a turbosmooth on top. saves hard drive space.. tbh though even without modifiers on top it still runs at only 2-3 seconds a frame.
