~0.1s is the limit after which there is a distinct delay between action and response. This is not the same as the point at which things feel instantaneous. > 0.1 second: Limit for users feeling that they are directly manipulating objects in the UI. For example, this is the limit from the time the user selects a column in a table until that column should highlight or otherwise give feedback that it's selected. Ideally, this would also be the response time for sorting the column — if so, users would feel that they are sorting the table. (As opposed to feeling that they are ordering the computer to do the sorting for them.) https://www.nngroup.com/articles/powers-of-10-time-scales-in-ux/ https://www.nngroup.com/articles/powers-of-10-time-scales-in...
