I get to like 500,000 bunnies before a significant slowdown. Yay!
My notebook with a mobile GTX 1080 manages to get to about 300k before dropping down (very suddenly from 60fps to 40fps for some reason. I would have expected it to be more gradual). Sadly, it seems to be locked to 60fps, so I can't check above that.
It seems to depend on the window size though, with a small window I can get to about 400k.
Mobile, I get to 80,000. I am very happy with that
