Test for someone with m295x, need to compare my m290x

I think that is a big part of it. Its not jerky every time I open mission control or a new tab in Safari so I'm wondering if 10.10.1 might bring some improvements. But i'm also debating ordering one with the m295x and return this one.

I messed with one in the Apple Store and noticed the same thing. Base model running in best-for-retina resolution. Seemed to choke more when the pro apps were open. It was pretty jerky scrolling around an image in Aperture.

Most users would be fine but photo/video folks should definitely spring for the GPU upgrade, though who knows how well that one performs.

converse to typical PCs, my original '12 rmbp performs way better now than when I originally picked it up over 2 years ago. How about that lol😱

So I picked up a base model iMac Retina. Everything was silky smooth until I hooked my other 1440p monitor up. Now mission control is pretty laggy. Remove the extra 1440p and everything is perfect again.

I would like to see someone test it out on the upgraded video card. I use mission control a bunch so I would be willing to return the computer and order an upgraded one if it is going to be laggy.

uploaded a video of it with and without the extra monitor plugged in:

http://youtu.be/S96D3z2JwQg

Wasn't as laggy as it sometimes gets in this video, but it shows what I mean.

Edit: Another way to test if you have an m295x, but no 1440p monitor, is to open up a bunch of windows and crank the scaling all the way to the top. If I do that on the 290x without the external display hooked up it can get laggy as well.

I have the 290x in mine, and my Mission Control performance is the same as yours in that video...without a second display plugged in.

Right out of the box, thats how (badly) it performs. No matter what I do, I cannot get the smoothness of Mission Control that you are seeing when you unplug your monitor.

For that matter...my 2012 mac mini with hd4000 graphics and two 1080p displays plugged in has smoother mission control.

WTF.

I wouldn't count on it getting better. My 13 in MBP exhibits the same thing, only worse when a second monitor is connected, and always has. I'm thinking it may just be a GPU limit. I wish I could use the display in target mode and load it up on a hackintosh partition on my gaming PC. It has a GTX780. We could settle once and for all if it is GPU.

This. I just set up my base model 5K iMac today and with just a few apps open, triggering mission control is a jerk/stutter fest. It's not partial lag, it's horrid.

Using 1440p 'best for retina' mode, non-scaled. I don't think it's going to make any difference which GPU or how much vRAM you have.

Damn it...

I agree, I cannot imagine that the slightly faster card would matter.
If it had anything to do with the card, things like minimizing genie effect and other animations would also have some degree of lag, but those are actually stunningly smooth. I have to assume this temporary and something Apple will optimize with either a firmware update for the card, or a Yosemite update.
 
Just out of curiosity, what happens when you switch the iMac's display to be 2560x1440 rather than 5120x2880? (I mean non-Retina 2560x1440 mode, ie the same as an older iMac would be doing).

Just wondering...

Well just try a 1280x720 image full screen on a normal 2560x1440 27" display and you'll get the same effect.
 
No, you'd need to use gfxcardstatus or similar to switch into a non-HiDPI 2560x1440 mode. And then it would be similar to a non-retina iMac, but with sharper-cornered pixels, presumably.

I actually kind of tried this before returning mine. What I did was knocked the 1440p extra monitor down to 720p. It helped a ton.

I think you've missed the point. I'm not interested in how it looks, I was interested in whether the lag which the original poster mentioned would be affected.

Probably would be similar. Perhaps a little faster (assuming the new Radeon is faster than the 780). But again, I was interested in the effect on the lag during mission controlling.

That's not quite what I was wondering about, but interesting nonetheless.

Cheers,

I tried different display modes, and the lag remained identical in all modes. Identical.

I really think its something with the display driver, or Yosemite itself on this machine.

Like I said, its not consistent UI lag....if the graphics card were under duress, it wouldn't be limited to Mission Control. Many other UI animations would be similarly affected if Mission Control were slowed to this extent.

Playing with the base configuration in store I also noticed navigating ‘About This Mac’ menu panes slower than usual. No stuttering, just an overall (noticeable) lower frame rate when windows were automatically being resized.

Indeed mine does this as well.

This happens on all of my macs with Yosemite.
 
Thanks everyone who tested this out, concerns have been alleviated somewhat. Now really interested in seeing Mission Control performance on a fully spec'd M295x model, or whether a software update to improve this is waiting to be pushed.

I'm also really interested in seeing if the m295x has the same issues with a few of the animations.

I'm pretty sure its a software issue with 10.10 and hopefully it will get fixed.
 
I ordered the Retina iMac (4GHz i7, 16GB RAM, M295X video, 1TB Fusion HD) the day it was announced and received it earlier this week.

The only time I have noticed lag was moving a window inside a VMware Fusion Win7 session while it was installing updates. The movement of the window was a little "stuttery". However, an Ubuntu session which was running at the same time and also performing updates suffered no problems. I would like to think that its a Microsoft or VMware video driver problem because the Ubuntu session was fine.

Mission Control and the rest of the UI has been very fluid for me.

I will say that my older MP is laggy with Mission Control/dialog boxes when I first start it up for the day or come back from sleep. I've read it's a spotlight indexing thing but I'm not sure. Now that my system has been up for 30 minutes everything is working as usual again.
 
Good news!

So I chatted with Apple Support and they gave me something to check that I'm embarrassed I didn't think of myself....creating a new User, open a bunch of Apps, test Mission Control.

I did, and the sluggishness was gone. It didn't even slow down until I hit about 20 App windows.

So, the support rep advised either migrating to that user and deleting the old, or just re-installing OS X.

I reinstalled OS X, and so far Mission Control is buttery smooth. Fingers crossed.

It seems the Yosemite install that shipped may be a tad wonky. I will report back if I experience anything different and would absolutely advise anyone experiencing the same thing to give it a try.
