Playback of an animated mesh with shape or bones is very slow with the subdivision modifier (2.8, 2.81, 2.82.7, 2.83) It is a very serious problem for characters and creatures animation.
I attach 3 videos.
The problem had been resolved in older versions of Blender (2.7) as you can see in this video where Sharybin shows a dragon flapping its wings (2014):
Just to clarify one thing, the Subdivision you’re showing in 2.79 runs on the GPU when “use OpenSubdiv” is enabled while 2.8x is always on the CPU, and AFAIK Blender playback is capped at 60FPS, don’t know why though.
Could you send me a link where the developers talk about this problem?
To switch from other software to Blender, basic functions such as opensubdivision (GPU) should be implemented with the utmost urgency, it is from 2018 that we talk about it …
They were talking about it when the old code was changed to open-subdiv but nothing has changed since then (https://wiki.blender.org/wiki/Reference/Release_Notes/2.80/Modeling#Subdivision_Surfaces_and_Multires). I like everything about 2.8 over pre-2.8, but subdiv part is the worst problem of 2.8, you literally can’t even model with subdiv on, you have to turn it off/on and you never had to do this before 2.8 for performance reasons. Please devs, if you are reading this, we REALLY need at least pre-2.8 speed back. Please
Agree ,need to turn back 2.79 speed. We already have 2.8, 2.81, 2.82 and seems 2.83 without fixing it.
Seems developers forgot that they wanted to turn 2.79 speed back before official release of 2.80. it needs to be fixed more then adding new features. Need to change it priority to high.
Without fast subdivision it is like going back 20 years. Ok Blender is free but productivity is much more important if you work with 3D.

Where are the open subdiv? Maybe better to throw in the towel, big disappointment …
