    Upgraded to Yosemite on my 5,1 Mac Pro and the UI lags hard, particularly when safari is open. All the windows and any video running seems to freeze, but my mouse cursor still moves and any audio plays fine while the UI is frozen.

    Graphics card is a AMD Radeon HD 7950 with two 23" Apple Cinema Displays.

    Tried this but didnt seem to help:

    Any other ideas?
    Thanks in advance.

    iCloud or disk index issue?

    I have a similar setup as yours with a GT120 card (yeah, I am waiting for the 980 from MacVidCards), but I am also running two 23" cinema displays, and I am not feeling lag at all.

    Try turning off safari sync on iCloud or restart your computer if the finder is indexing your drives. When I first installed Yosemite, it indexed my drives -- did not slow them down, but it was really annoying for quite a few days.

    I also have multiple 3,1s running Yosemite without a hitch on previous gen hardware, so I really think that your issue should resolve itself, or perhaps you should reinstall Yosemite.

    Thanks for the advice, Safari sync did not work and its still lagging. I am going to stick with Chrome for the meantime as it seems to avoid those issues.
    If the next update to safari doesnt fix it I guess I will be forced to reinstall Yosemite clean

    Welcome to Yosemite, basically.

    Loads of people are reporting UI lag, I have it on more than one Mac, clean install or not.

    I turned it off because I just don't like it:eek: I didn't notice a change in performance.

    Interesting - i have a GT120 pushing a 30" ACD (as well as a 24" dell to the side) and it's terrible with Mission Control, much worse than Mavericks. Even if i remove one of the monitors (i.e. just running the 24") it's still very sluggish - Mission Control is lucky if it gets 2 frames of animation! Horrible.

    Turning off transparency doesn't seem to help at all.

    It doesn't really bother me as 1) it doesn't stop anything working 2) i assume it will improve with 10.10.1 and 3) i'll be buying an AMD r9 280x or similar soon enough.

    But it's interesting that you don't have issues... and slightly disconcerting that a 7950 owner is!

    In the interest of solving this particular problem, I should mention that I have dual x5670 hexacores and 64Gb of fast memory on my 4,1 --> 5,1 mod. So it is quite a bit more powerful than the op's system except for the card.

    Hi

    I have the same problem (MacPro5,1 with W3680 and R9 280X) and my Safari (and Webkit) is lagging while resizing the window.

    But it only happens in a window with content. When I open a new empty safari window I don't have any lagging.

    It even lags in this editor window while writing this message.

    So I think it is an Safari or OSX Yosemite Problem.

    Denis

    PS: Iam running the 10.10.1 beta, btw.

    Everything about Yosemite sounds a complete mess.

    This is Safari's problem, I finally switch to Chrome because of this reason.
