"Until thorough benchmarking is completed by me or someone else, I think the best way to put it is this: Task View often runs at 60FPS, while Mission Control never runs at 60FPS"
So, it seems that in this case a beta version of Windows works best than MacOS
How buggy was it, really? I've heard several painful stories, but nothing concrete, except some changes Apple made to the DNS infrastructure.
The same kind of stories I've heard for every release since 10.4, about how the new one is so buggy, etc. Then, the next release comes and people wax nostalgically about how stable the previous one was.
Yosemite was bad enough that I do not accept Apple updates until a few months have passed and I know what the fallout will be based on complaints on websites. List of broken things
a) Battery life on my macbook pro plummeted after the upgrade.
b) I get visual artifacts (black lines on screen and some flashing) when OSX auto switches between the intel gpu and the nvidia gpu.
c) Cannot get nfs transfers to work with acceptable speeds (they seem to top out at 2 MBPs)
d) Broke drag and drop in Qt because of some changes to the string supplied to the drop event.
e) Bottom of my macbook pro gets unacceptably warm. I dont recall it being this bad before the update.
a) same battery life as ever on mine. Even better actually.
b) Seen some occasional flashes. Not sure why it happens, but I think it's related to the color temperature mananging "Flux" app (they seem to stop when I don't use it).
c) Sure not some network problem? I've had succesful NFS transfers, but usually small files, so never bothered to check.
d) Shouldn't Qt fix it? If it didn't broke drag and drop in native apps, then Qt emulated it based on some assumptions that weren't guaranteed.
e) Never had this happen, even when using Compressor on all cores. Top left might get a little warm at those times.
I have about 50 to go by and given the stats, it crashes more often than Maverick and much more than Mountain Lion. Wifi is a constant pain (although iOS 8 is much, much worse with about 75% of the iPhones and iPads refusing to work with our Cisco network - no other OS exhibits this randomish behavior).
It also is a memory hog compared to Maverick and earlier. 4GB machines are noticeably sluggish (to the point of user complaints).
Yosemite likes to crash hard when it is put to sleep at home then plugged into a thunderbolt monitor at work. This has happened quite a lot to multiple machines and I have no clue. Add to that the buggy Finder from Maverick and I am getting complaints. Its time for another Snow Leopard.
I agree 100%. Apple needs to devote an entire release to stability and gaining back its reputation for stability. At the moment absolutely beautiful hardware is being ruined by cruddy software.
Yes 10.10 was released at least a year too early - it really should not be out of beta. I get daily "pizza wheels of death" with 10.10.3 on my Mac Pro. On the same machine I have yet to have Windows 8.1 crash. The hardware is fantastic, the software far less so.
btw did you do a fresh install? I'd always just upgraded and had no problems; until Yosemite. It's a bit more time consuming but Yosemite has worked great for me since I did a fresh install.
I did a semi-clean upgrade. I bought the Mac Pro late last year and it stil had 10.9 on it. I upgrade to 10.10 before copying across my user files and software from my laptop running 10.9. I have been trying to figure out what the cause is by looking at the crash logs without any success. I do find that daily reboots lessens the risk, other than this there does not seem to be any rhyme or reason.
I have been using MacOS of various stripes since 1990 (I am a biologist by background and biologists were one of the few groups that stuck with macs through the late 90s). Other than 10.1 Yosemite is the buggiest OS 10 release to date in my experience.
Interesting, I was in the same upgrade boat, but went back to 10.8 on my Mid-2011 MBAir. With only 4GB of ram, 10.10 was killing me, constantly spooling up the i7 & fan to screaming levels.
I have a hard time understanding the equivalence. Is task view supposed to be representative of all windows programs ? Is Mission Control supposed to be the fastest OSX program ?
I don't use windows So I'll also have to ask, are these programs actually comparable in what they do ?
Yes, Task View and Mission Control are similar. I don't think that this speed comparison is very useful, but in my experience the graphics drivers under Windows are significantly better than on OSX or on Linux. (I run Ubuntu, OSX and Windows 10 on my retina MBP, and desktop graphics performance on Win10 is way better than the rest. By 'desktop graphics performance' I mean window management, scrolling of 2D content in browsers and other apps.)
However, Win 10 runs quite inefficiently on Apple hardware in terms of battery life.
On a side note, I find Win10 as the first Windows that is usable on HiDPI machines.

An influence from its gaming heritage? I know that GPU companies definitely spend a lot more effort on improving their Windows drivers than on other OSs, because of gamers.
That and the fact that Apple just doesn't seem to care much about 3D support... the 3D stack is about 3 years out of date now, GPU drivers as well (and nVidia etc. can't update them). Yosemite had NO updates to the GPU drivers or OpenGL support at all and currently it's still about 20-30% slower on the same hardware compared to Windows.
If I'm a bit cynical, Apple is deliberately refusing updates just so they'll be able to tout huge 20% performance improvement of their proprietary Metal when they bring it to OS X.
I'm using Windows 8 on both a rMBP (~220 PPI) and a 4K 28" monitor in the office (~150 PPI). It has worked fine for awhile, the only problem are some legacy apps (e.g. font forge, the font installer, and oddly enough, BootCamp!).
I'm finding Mission Control a bit slow too. The whole Exposé thing was a lot snappier when they still called it that.
That said, in Task View on Windows do the iconified windows still play live content? E.g., under mission control, a video window will continue playing video live in its preview texture. Does this happen on Windows too?
So, it seems that in this case a beta version of Windows works best than MacOS
