lag and stuttered scrolling on riMac 5K?

[niklasios]

Maxed out riMAC

That NASA pdf lags when on fullscreen scrolling in preview.

Netflix won't work but that appears to be a Yosimite issue, not the Rimac

heres a video of the lag:

smooth scrolling in safari, followed by lag with preview. lag also present in other apps (evernote, iPhoto).

There is absolutely no logic in returning your iMac. This is a software issue and Apple is aware of it.

Have a look here too: https://discussions.apple.com/thread/6624344

Just returned from the Apple store to play with the base riMac and reproduced all the stutter and lag talked about. I did the same on the non retina and no lag...it was running Mavericks though. In my opinion you should get at least 16gb ram and the 295 card when if you aren't doing any heavy lifting. I am coming from an i7-3770 with 16gb ram and an hd5770 windows box.

yes, this is similar to what I'm seeing on my 5k iMac on this particular PDF, thanks for showing us exactly what you meant.

I still think the choppy scrolling (somehow that seems to speak to me more than "lag", which implies a delay) only becomes a problem when you are at full screen and zoomed in. We all have different tolerances and expectations I guess.

this seems to be a feature of other retina devices (18 page apple.com thread here => https://discussions.apple.com/thread/5547471?start=255&tstart=0) -- not just my iMac.

there is no stuttering on safari, nor apps that i more commonly use. i have only found it to be an issue when dealing with preview, evernote and iPhoto. granted, these are just the examples i've come across - there may be more i may notice in the future.

can you really do preview, full screen, with the .pdf above zoomed in a bit, with the continuous scrolling setting on with no lag/stutter? if you have a lot of thumbnail events, can you do full screen zooming in and out on iPhoto with no lag? if so... then i guess i should return...

but it appears that a few other people are observing this lag, which makes me think it's not an isolated event.

i don't think this is a dealbreaker for the machine though.

The only lag I see visually is the Mission Control, which according to Apple is getting fixed in the next update. This is on base model with 4k external attached.

I do not have thumbnail events in iPhoto, Preview has no stuttering in PDFs.

AFAIK, they only acknowledged the Mission Control issue.

I get no lag with the NASA PDF in regular view; no lag but a crash in full screen.

I tried in on a 2010 iMac. Same result.

So not a riMac issue; maybe a PDF, or OS 10.10 issue.

pioneers... ha.

so people can really use preview to browse a big .pdf with no lag (continuous scrolling option, full screen)? if so, this would be helpful to determine if i need to return it...

example pdf => http://www.nasa.gov/pdf/750614main_NASA_FY_2014_Budget_Estimates-508.pdf

.pdf browsing in safari appears to be smoother...

It seems to be a Yosemite issue, in my rMBP 16gb RAM in the Mavericks partition works smooth, however under yosemite scrolling and zooming is laggy as hell.

32gb of Ram, 295 card, 1tb SSD and i7 riMac here, still lagging, i've got the maxed out one.

def. a Yosemite issue but still was enough for me to walk from the store without buying the base model...that being said MC qas only stuttering when there were a dozen apps running not when it was one or 2....still $4100 CDN for the i7/16GB/295/256GB SSD is a lot of cabbage...

I think its a common problem with Yosemite in general. It will hopefully be better. I noticed, both on my new iMac retina and my previous iMac (late2012) that a lot of stuff seem to have more stuttering in Yosemite. I think the new semitransparent,blurry effect cost a lot more than what OSX used to. THough, its not really bothersome, I have other issues with OSX that bother me more, which seems to never get fixed from apple. Such as: Finder bugs/hangups (this started appearing in Yosemite though), Finder SSD problem that newly added files aren't always visible before new changes are made to a folder, FontBook being extremely slow (this has been around for ages), etc.... ALl of these problems are something I experienced on my previous iMac and now with the fresh installed new iMac, so its not a unique problem.

I have this same issue with my 2013 27" iMac. Force Quitting the Window Server process and logging back in fixes it for a few days.

NASA pdf, no lag. Base model riMac with 16GB ram. This Xbench dude, you know that xbench is almost 9 years old?

If you wanna push GPU in OS X for OpenGL testing, here you go:

Even 6970M is way powerful than 6750M, M290X is about 2-3 times better than 6970M.

Oops, the testing dude was in appleforum...

I don't get any lag on my RiMac from that PDF in Preview

Mine worked just fine (i5, 290, 16GB, 512 SSD) - On a related note, holy huge PDF, wonder if he read it all
