I work on a heavy scene.
when I play animation with spacebar frame rate is 19 and its good. but when I change time manually with time slider is very very laggy
also when disable bone dynamics , bones are dynamic when I move on timeline with arrow keys.
also with make a bobe dynamic it kills software. every freeze keys, delete keys and ... take more than 30 sec

Have you checked for unintended negative keys? If you don't have Wes' Delete Negative Keyframes tool, go here...

Be sure to make a copy of your project before running the script. If it finds anything, deleting the unintended frames should solve the lagging UI the problem.

Hi friend.
I used that.
It did not matter.
absolutely I am sure some thing is wrong.
1 .with empty scene please turn off enable frame skipping . play animation. you will see frame rate drop to 21. why? normally it must goes up to 240 for example.
2. create a scene with import a character from moho library . duplicate is 5 times. now hide all of when. now play animation. its good. but please move time slider manually , you will see its very laggy.
3. and i know there is a problem with dynamics. some times It doesn't work. if you want I can share with you the scene have problem.

Frame rate should not be faster than the project frame rate. Unbaked physics can cause that, but others have found that updating GPU driver can help.

Not significantly laggy here.

Dynamics have to played from the beginning, so they can be properly calculated. Playing from the middle of a dynamic animation will cause sudden jerks.

No it's not true. when frame rate isn't limited it allows to go up or down based on hardware specifications. also with disabled frame skipping frame rate Should not be reduced when scene is empty.

even is empty scene it happen.
but others have found that updating GPU driver can help
driver is updated.

i will create a video to show.

yes.it's true. but it completely don't work some times. I send you an example later if you want.

Software should not try to play faster than real-time framerate. That would be useless for animation timing.

Then we need some repeatable steps to replicate the problem. Otherwise it's likely something on your system.

Don't bother. I think I've already helped you as much as I plan to.

We try to find bugs. I already solved problems that i said.i spend my free time to report and suggestion. Again here i dont want any help from any one.i just report problems.
where you help me was in programing topic. Thanks again for those.

Yeah, I'm done helping you with that too. Yer on yer own, kid.

for solving problems I use alternative solutions.

for dynamics problem I disable that and do it manually.
for lagging time slider I select my character and use copy layer and send it to new file. I animate character and send it back to previous file with copy layer.somr times I render file as a png and import to main file as a image sequence.

Yeah, that's a valid technique. If the rigs are complicated (i.e., lots of bone deformation for high-res images or lots of dense meshes) and you have many keyframes, Moho can bog down when several characters are present.

This is true for many animation programs. Years ago, I worked on a sequence for the Croods TV show using Toon Boom and I had 17 characters to animate. They didn't do much in the sequence but animating the rigs for each character was painfully slow. I wound up breaking the scene into separate projects with fewer characters in each (about 4 or 5 from what I recall,) and then compositing the rendered characters into a new project. I don't think I've ever had to animate nearly that many characters in Moho yet, but I do occasionally pre-render complex characters and composite the image sequence versions instead. It's really not unusual to animate elements in multiple passes...I do this for 3D animation and VFX work all the time.
