Scene animation has always been choppy?
« on: May 29, 2020, 06:02:33 pm »

Idk if this is just me of if everyone experiences this...
Since my last several PCs (basicaly everything after Windows Vista) I can't remember ever having Scene view play in realtime to the frame or playback an animation any faster than probably about 6-10fps.

Is this an issue with my hardware? @Steve anything I can do to optimize playback for easier animation in Scene mode? Trying to animate a character but it's always been tough judging 'weight' and all those animation-principle things when not able to see everything happening as it will render  :'(

How complex are your scenes? How large are your models, how many, do they use morph targets or are rigged with deforming figures? Also, what CPU do you have?

The character I'm working on is a subdivide, but only 556 points altogether. I get (of course) better framerates when displaying him with fewer divisions and particularly when the Track view is collapsed (which I never realized.... seems like the track fully re-renders of something every time the marker moves a frame?)

Also I guess with that I found out it IS playing in realtime, but dropping most of the frames to gie a total of those 6 - 10fps (with the track opened up and a high-ish poly model with low divisions)

He DOES have 10 morph targets for facial expressions and I like to try to zero them ALL out any time I'm changing multiple aspects of the expression, so plenty of key frames :S


My CPU is an AMD FX-8300. Does Anim8or lean toward Intel? Or possibly newer-gen CPU types?

Oh meant to say, this is pretty simple - one instance (object?) made up of 5 smaller objects within the scene

 I had the same issue some time ago, and a good nVidia graphics card did the trick.
 Have got a slightly better PC now, and first thing i did was put a decent graphics card in.
 Not playing in realtime, 24 - 30fps, but quick enough to watch.(simple scenes)
   Gotta do a quick render to watch at full speed

No specs on hand, but i have read that  intel are a better cpu

 I'm not really up on all that, but did enjoy updating my 'older' pc to a slightly better one.

 just a thought. 

 Another thought. Anim8or is easy portable, maybe you could copy your project to a usb stick and try on another pc with different specs

Well it's all about how complex the scene is
I have a dell precision m6700
i7 3840qm(~3.8ghz)
k5100m
32GB

And dell xps 13
i7-10510U (~4.9ghz)
Intelģ UHD
16GB

I pretty much get low fps if the scene is complex...and subdivided
But if I remove subdivision I can get +-32fps on both machines

Good thoughts johnar. Iíve actually got a pretty decent GPU in here so I doubt thatís the issue 🤔 I might try to do the actual animation from my laptop which has a good Intel processor but no on-board graphics.

How complex do your models/scenes get as far as number of points and number of objects in a scene?
I can get it to maybe 15-20fps if I set my subdivisions to 1, but of course going down to 0 makes the model too low-poly to really see whatís happening (I guess I mentioned that before).

When you do it do you usually have the timetrack showing? That seemed to be the second-biggest factor in determining the playback frame rate.

(What made you go with more RAM on the slower processor btw? Or is it a desktop and laptop for example)

@davdud101  Both machines are laptops...I did not upgrade or change components of either so m6700 came with 32GB...xps with 16GB

points.jpg : shows total points unsubdivided
sub_points.jpg : shows total points subdivided
complex_sub.jpg : shows 2.14 f/s (5 of that guy it means atleast 1.2 million points)...any complex scene could contain as much points or less
complex_unsub.jpg : shows 22.2 f/s (the number changes everytime...from +-22 to 32 max *I don't know why)

I can't upload more pictures the other results only with one guy still goes from  +-2 to 7 (subdivided)
and 30+ unsubdivided

That's a decent CPU for a laptop. I think that the main issue is that those are very high face counts. You really don't need nearly as many faces. And each level of subdivision increases the face count by a factor of 4. The subdivision is done in software after skinning, which is faster than the opposite order, but it still takes time.

For my part I'm finding I just need to learn to downscale all my subdivided objects to more of a 'preview' quality and it gets me a lot closer to framerate. I can imagine it'd be the same situation for any graphics application. Seems weird saying this because I realize I have sooo little experience doing actual animation in Anim8or xD I use Scene mode a lot for making quick renders for mockups but it's been years since I actually tried animating a character, haha!
