Slow animation playback in Eevee Rendered Viewport



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?
