Why is it a problem for you that the CTI isn't moving or being drawn smoothly? You say that the playback is smooth and everything else works correctly, yes?
This may very well be a bug/glitch, but I want to understand whether it's just cosmetic or it's actually interfering with your use of After Effects.
Yes everything else works fine. Im doing alot of intensive audio syncing and altho i make great use of all the various other tools for that during the finalization stages, the ability to simply watch the cti during previews definitely helps me to get general feel and ideas for positioning and rough ins without spamming markers or deciphering scrub sounds too early, i can also quickly position main keyframes during just audio previews without waiting for full video preview in heavier comps. Its small things that add up and it generally speeds my current routine up in various situations. Iam doing alot of precise sync editing in NLEs too, and its even more about the cti there so i guess i might be just too used to it and now it feels wrong when it suddenly doesnt move smooth in AE after i switched os.
I would at least like to know whether its "officially" supposed to move smooth in vista/win7 just so i dont spend all this time investigating the problem only to find out that its actually jumping like this for everyone and they just dont care. Because ive tried close to everything by now and still cant find the cause.
Found two older threads about the same problem on creativecow:
alrite i managed to find it, so just in case someone else has this problem... in ae preffs file theres line "Time needle update frequency (seconds)", change it to what you want.. this is probably automatically set to a specific value during first ae launch after installation based on what os/hardware the given computer has. So i guess it sees that i only got 4gigs and am running win7 / vista, so it tries to improve performance by drawing cti slowly
