Slow Playback of mocap data I downloaded Animations from mixamo to import into my scene. In the mixamo webapp the animation plays back at 100fps. In Blender 2.8, its 7fps.

Solid mode, no modifiers, no materials. No other objects in the scene but a plane. Purely the imported FBX from mixamo.

What could be causing the framerate issues? Is there a way to remedy it so that the animation playsback at 24+ fps?



Currently running a Dell Insperon g5 with a gtx1060m and an Intel i5-7300hq 2.5ghz and 8gb of ram
I found I could work around my issue by optimizing a few things. I want to stress that these are all to lighten the load of the CPU during playback and I have not found any way to make Blender's playback as reliably smooth as Mixamo's web player or Maya. I suspect this issue stems from how Blender's code handles hardware acceleration during playback. Something that would be far outside of my realm of expertise.

OPTIMIZING:

Models -- 


Merged Unconnected overlapping Faces(Merge by distance)
Remove Doubles
Tris to Quads
Apply Decimate modifier for a low res proxy model.
Erase nonessential faces from low poly proxy model


Viewport: 


Use WorkBench
Shade Single if possible


Ui:


Remove as many panels as possible, this includes N and T menus.
Ctrl+alt+space to fullscreen for smoothest playback


Misc:


remove any VSE Preview panels

1a. If you need a vse preview panel, set it to the lowest resolution proxy settings


In Solid mode, with these changes I was able to go from 7 fps to 45 fps with my single character 
In Eevee the difference was from 2fps to 14fps for the same scene.

Not a perfect solution but certainly a significant performance improvement, especially in solid mode.
