Anything that is above a netbook or a sub $500 laptop doesn't lag and today's computers and phone are spoiling us. I have a 8 year old netbook and I run a minimal Linux install with a tiled window manager and it is quick. I also have an i5 Sandy-bridge desktop and I also work with a tiled window manager because I prefer it, but my wife has Windows 10 on the same computer and it is spot on and that is 6 years old. My video work station is blazing fast and it never lags on anything except chugging through 4K/8K video renders.
