maybe you’re doing something different from everyone else or your expectations are too high, but three finger swiping to move between spaces on macOS should feel smooth and buttery. There's a 200 millisecond lag after you switch spaces and when your input gets rendered (it starts accepting input in the new space as soon as you switch) that, if you're staring at that and focusing on that, watching it like a hawk, exists, but if you can get over that, Spaces/virtual desktops is a useful feature. The whole screen needing to rerender shouldn't be happening. What apps (or more likely, your IT department) are you running?
