Just installed this version on my Windows 7 Pro 64 bit machine a few weeks ago. When I paste in package code (e.g., 2000 lines), there is an annoying noticeable lag as well as a lag when clicking a new tab in the Editor.
Initially I imported the settings from my old version (18.104.22.168) where this situation was not present. I then disabled all code assist options (except ctrl+click to describe or jump to objects), disabled auto replace, and anything else that seemed to slow it down, re-booted machine, etc., but nothing has changed.
Any hints or a list of recommended settings would be welcome.
