Performance degradation after the new update
This may be anecdotal, but after yesterdays 400MB update that added compute shaders, Dota 2 went from 60fps stable @ 1440p on my Radeon Pro 560 4096 MB to struggling at 30-40 fps. I had to lower the graphics quality one notch (in the automatic settings slider from high to medium) to make up for this.
Anyone else noticed the same?

I measured a performance gain from compute shaders on my AMD FirePro D500. Does toggling Compute Shaders have any impact on perf (keeping the settings at high)? A performance drop would be unexpected.
As a comparison, I'm seeing a ~15% performance boost with compute shaders on my iMac radeon 580, macOS 10.3.5. With shaders disabled, I think performance is roughly the same as before the update.
Im actually experiencing the same thing. Playing a full match with compute shaders on would result in the fps tanking to about 20 to 30 fps on my case.
they work fine on manjaro linux intel iris crystallwell C220 Chipset until minute 27 of a match. Then stuttering with still max fps
@danginsburg How can I get you quantitative analysis of this problem? Do you have a tool that can profile fps/tick/replay? I can play a game each with both on and get you the replay, but I don't think that information is tracked in the replay files.
I can also test it for you on my desktop which is running Gentoo (4.17.6, and I can emerge vulkan support to test) but I don't think it will be noticeable because its a 1080GTX.
