Slow animation playback in Eevee Rendered Viewport

#1

Hi,

I recently downloaded the beta for Blender 2.8 and a couple of the demo files (treecreature.blend and temple.blend) to test how fast it takes to get a rendered result with Eevee, and I’m trying to play back the animation on this fully rendered setting: image

Only problem is that playback is barely 10fps for either file. Even navigating around in this fully rendered view was impossible. I assumed this was my graphics card, so I swapped my 4GB Radeon RX 460 for a 6GB Geforce GTX 1060 (since I was also told Blender gets along nicer with NVIDIA than AMD cards on Windows 10) to see if that would fix the issue.

Thankfully, I can now navigate 3D scenes and easily move lights and objects around in a fully rendered Eevee viewport with zero lag. However, I get the same awful framerate with an animation playback, leading me to believe this might be some sort of bug.

I have an AMD Ryzen 7 1700 CPU and 16GB of DDR4 memory with an SSD on Windows 10. What should I do?

I’ve got this issue as well.
Moving around the viewport isn’t laggy, but as soon as I start playing an animation with a complex rig it’ll crawl at around 5fps, whereas 2.79 plays it back at 30fps.
Doesn’t matter if I use workbench renderer, it doesn’t seem to improve the frame-rate.

I’m having the same problem. It used to play at 30fps just fine, now it’s 20fps at most. I don’t know what changed. Can anyone help?

I’ve noticed animated armatures are a big issue here.
Blender 2.8 is so much slower at handling them unfortunately.
And if it’s complex, like a rigify armature, then oh boy. It’s bad.

I filed a bug report way back about the general slowness of viewport animation but it fell on deaf ears. I might follow it up but I’ve already submitted 3 bugs today.
