    For some reason, I couldn't search effectively on these terms, so I decided to back up and load 10.10.3.

    Well, Preview is indeed better, but still un-usable. On a scale from 0-100, it goes from 3 to 7. It opens my file (PDF) better, but as soon as I zoom in, one of the cores goes to 100% CPU usage, and stays there, making any subsequent re-sizes or moves incredibly difficult.

    Yes, I filed a bug report on this, and I even gave them the file for a benchmark. There's nothing wrong with the file, it behaved perfectly in Preview pre-Yosemite.

    Oh well.

    just checked, and both of these things are working fine here, so something specific to your setups... (am running 10.10.3...).

    I have a large variety of them, save a Mac Pro.

    It's not a model-specific issue.

    The reason I ask is because I have Yosemite installed on 3 Mac Computer, 2011 iMac, 2009 MacBook Pro and 2009 Mac-Mini and have not experienced any issues with Preview. I thought maybe it is related to retina display Macs.

    Preview performance is definitely worse in OS X Yosemite. I've noticed that as well on my 27-inch iMac (Core i7 3.5 GHz, NVIDIA GeForce GTX 780M). It's definitely not the hardware...
