I wanted to show you three pictures of frame time traces from a forum user who only yesterday had a microstutter problem that in this case was caused by a driver fault where the clock speed would drop during the game. An upgrade to Catalyst 12.11 resolved that problem and smoothed out the gameplay. The orignal thread http://forums.anandtech.com/showthread.php?t=2289212 is available. Many thanks for LessThanDan for providing this information as it gives us a study in a game where we have different amounts of stutter being shown. This is a user who perceived microstutter and thus it allows us to understand how much is too much at least at a granular level (for Dan at least).
Here are the traces and the perception that went along with them:
Really bad, not smooth (Hitman High settings, clock speed fault):
Not smooth but better (Hitman Medium settings, clock speed fault):
Solved, felt smooth (Hitman High settings, clock speed working):
Dans tolerance seems to be swings of 5ms or so and occasional drops to 25fps, both he is happy with. Having tested my own its also 5ms and drops to about 30 fps. What is yours?
