So today I bought a new 2015 13" Macbook Pro after finally giving up on waiting out Apple for a retina display on my aging Macbook Air. I am experiencing extremely poor GUI performance.
I know that retina displays are taxing on GPUs, but the Intel 6000 series seems incapable of driving this display without extreme choppiness in Yosemite for a number of actions— mission control, switching between windows, opening new windows, etc. This is the most significant lag I've experienced on any laptop on Yosemite. My old 2010 Macbook Pro 13" doesn't lag this bad on Yosemite.
Is this the experience of others here? The performance is so bad that I'm going to return the laptop if it doesn't improve because it severely impedes on the usability of the system. Also it is BRAND NEW!
UPDATE: Resetting the PRAM may fix this issue for you— it fixed it for me.
Double update: So yeah, apparently this is a widespread problem. I figured I'd provide a final update: The PRAM reset fixed the problem for a few hours and then it promptly returned, even on a fresh install of both the 10.3 beta and the 10.2 stock with no 3rd party programs running well after the housekeeping processes completed. When using an external 1080p monitor, I experienced display lag so bad on mission control and spaces that it prevented me from using the laptop efficiently, which is unacceptable IMO for a brand new laptop. I eventually returned the Macbook Pro to Apple, and I'm going to wait until the next revision of the laptop to upgrade. My Macbook Air from 2013 continues to have fantastic performance— silky smooth with tons of 3rd party programs installed
