steve: here is the missing file, I didn't use it for the texturing nor the file that you already found, file 'texture0' is missing but it's the same as 'untitled 2'.

trevor- on my computer(i3 CPU, integrated graphics) it plays in sequence at 30Fps, in scene 16Fps. I've tried to open it with few older versions of anim8or and the results are similar.
The only thing that speeds up the play preview a bit is to hit the wireframe mode button, if everything is hidden except bones then it goes at full speed. It's interesting that moving thru the scene with time slider allows much faster preview

The only time I get less than 30 fps for any scene or sequence is with 4 views, flat rendered with lines shown.  I have an I7 with a GeForce 960. I noticed that the head has far more faces than necessary.

I suggest reducing the subdivision level to just 1, or simply replacing the head with a simple sphere.  If you set the divisions to 16x16 or 32x16 it should look fine.

 thanks for the idea, interesting- I just changed subdivided head to mesh which gives 30Fps at preview in scene and no lag at all. Scene mode 'likes' meshes :)
 update- render time for camera view is almost twice faster when all the subdivisions are converted to meshes

Steve, what i7 do you have?

i7 is a catagory and means "Performance", where i5 ="Efficiency" and i3 = "Value"

The Specs of the chip are in its name, i.e. Northwood, IvyBridge, Haswell, Broadwell etc

As for the model, Ill need to try it again later to see if there are any differences between subdivide and mesh at the same polycount.

Oops, I was mistaken.  My current development computer is only an i5-2400 3.11 GHz. I don't know the name.

I too was mistaken, the name is its manufactoring size (eg, 130nm, 22nm, 22nm, 14nm etc)

You were right to provide the number, as even within each lithography they divvy up the specs.

I havnt closed any other open apps as I am working on them, but converting the subdivide to mesh (same polycount) results in a 0.2 fps increase from 3.6 to 3.8 in scene mode. (I ran it repeatedly and took the average)

OGL is running is software mode at this time because of the other apps open (even though PerfectGold uses DirectX)

When I take a break, I will run the scene again in hardware mode.

However, as steve has already indicated, you have modeled excessive faces on the head, eyes and hands. :P

I guess that the speed of the workspace and render depends on many different factors, and it is obvious that different computers give various effects. If I knock down the polygons on the hands, eyes and head then it wont look smooth and that's not acceptable. Slowed down wireframe mode is the thing that is very strange, it shouldn't be so slow, but I guess that here is the main issue weak integrated graphics card.

Wireframe is no different to solid if you use transparent faces.
If you uncheck that then wireframe is faster.

Trev

Hardware mode:
Sequence mode subdivision 31fps
scene mode subdivision 15fps

sequence mode mesh 31fps
scene mode mesh 20fps
scene mode mesh wireframe (No semi-transparent faces) 22fps

If the project is saved and reopened it also makes difference, gets a bit faster.
