I baked a simulation with 256 Resolution Divisions. It looks great, but my viewport performance is absolutely abysmal. I tried using simplify to lower the resolution but it doesn't seem to be taking effect. Should I have activated it before baking? I'm not sure.
I also tried tinkering with the "Viewport Display" options inside the Physics panel of the simulation, but it seems like nothing bumps the FPS past 2-5.
Just to make it clear, I have no problem in redoing the bake if it means performance increases.
