Seeing acceleration of the scopes?

BM claims improvements for the performance of scopes in 15.
I can't see too much of that in b2 on a 2017 Retina iMac, anybody noticing substantial differences?
If so, which platform?

rarely use internal scopes, only when i'm conforming/editing and the real scopes mon is turned off and i want a quick look...

that said, i see zero diffrence on a dual xeon /dual 1080Ti / 128g ram system, but i never felt lag or any slowdown due to the internal scopes being turned on anyway

maybe on a marginal machine like a mac laptop?

Then even my decent 2017 Retina iMac is too good

They're still incredibly slow if you set the external monitoring to 4:4:4 in the project settings.

I know it's been said many times here that scopes require a lot of computing power. But, if you set the data level to "Full" they become just as fast in 4:4:4 as in 4:2:2. Looks like a bug to me.
