just today i finally risked updating to 5.5.4 and noticed right away that the viewport feels a bit slower. after restarting my computer and thus also rhino nothing changed it still feels more sluggish. to be sure i reverted back to 5.5.2 (which is the only last version i had lying around) and can confirm that something happened there, not extreme but its noticeable.
i am aware that its a bit of an older computer but i am having AA turned off entirely.
