2012 15" rMBP Performance on OS X 10.10 Dev Preview 6

[jaycarroll]

Performance with the latest developer preview of Yosemite has been verging on unusable IME, even dragging windows would lag substantially.

The 'fix' for me was checking 'Reduce Transparency' in Accessibility. UI animations are now perfectly smooth.

Hopefully the GM will mitigate this a bit, but I'm not expecting much improvement where transparency is concerned. The 1st Gen retina models are right at the edge of what is required to push a display of this resolution.

So, just an FYI to others that might be complaining about performance in 2012 and earlier models.

Hm, I have a 2012 16GB rMBP and I don't see any significant performance regressions from Mavericks apart from switching spaces using a mouse gesture (keyboard is much better). The performance of switching tabs in "About this Mac" is also poor, but this has been the case since forever. Dragging windows, even across desktops/spaces is fine here...

Note I also use 1920x1200 HiDPI mode, which is considered the worst resolution for performance...

Great, that's good news, maybe there's hope yet. Although, it does feel about the right time for an upgrade. I think I'll hold out until the big refresh next summer.

BTW, I'm also running at 1920.. I'm pushing two external 24" monitors as well, but I also tried with them disconnected.

Yosemite is way smoother for me on my 2012 rMBP... its weird that experience differs so much
