Has anyone used this to test browser input lag?

  • Just wondering, if anybody has used this http://www.vsynctester.com/ to test their browsers for input lag?

    And if you think this is an accurate test?

    And could someone apply this method to a capx for testing purposes?

  • The vysynctester site was used a lot last year to prove to the Chrome devs that Chrome had broken vsync. It only shows you if your browser is dropping frames and causing jank whilst performing a simple image manipulation. You can check whether your c2 game is causing jank yourself by logging the number of times dt is greater than approx 20 ms (at 60 Hz dt should be 16.7 ms). Alternatively, you can press F12 and record your Timeline in the debug mode and it will indicate when frames were dropped.

  • Try Construct 3

    Develop games in your browser. Powerful, performant & highly capable.
