Animations want an extremely stable and consistent frame rate in order to present smooth motion: if that framerate can be sped up without burning your CPU/GPU/lap then that's great, but presenting ASAP gives worse results than a fixed cycle. Even games don't want to 'present ASAP' with no idea of when ASAP actually is. They need to build their scene with a particular time in mind, and then show it to the user as close to that time as possible. They are a little less sensitive to the need for a constant refresh duration than animations are, but they still need to know the exact frame display time in order to not look horribly jumpy.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
