However, it’s essentially useless, so don’t be fooled into thinking you’ll suddenly have a better viewing experience. You can use it to enable Retina HiDPI mode on old Macs that don’t even support Retina display (which was one of the big hints some time ago that Retina displays were coming to the Mac ). It can also be a way to instantly see the performance gains offered by tricks like this one to speed up up Mac OS X Yosemite, especially on older hardware. However, it can still be an interesting way to benchmark some aspects of Mac OS X, or at least see how specific activity affects visual performance on a Mac can affect. In the same way, you’ll find yourself using something like Increase Contrast, which turns off the transparent effects and interface elements become more defined has a side effect of increasing the FPS and reducing the CPU load during those kinds of tasks.Īs a developer tool, this is usually for testing application performance. Even something as simple as resizing a window or scrolling through a Finder window with Mac OS X Yosemite transparencies is remarkable. With FrameMeter enabled, you must interact with Mac OS X or an application and see how frame rate and processor usage are affected. You will notice that the FrameMeter looks like some sort of small dashboard tachometer, displaying FPS and CPU usage simultaneously. This short video below demonstrates how to use Quartz Debug for a live FPS view: When the FrameMeter is displayed up place, it is somewhere suitable for your use and start interacting with Mac OS X or an application to see how the FPS and CPU meter changes live so you can see the frame rate of the activity on the screen. Pull down the “Window” menu item and choose “FrameMeter” to display the live FPS and CPU monitor. ![]() ![]() On the mounted Graphic Tools disk image, open the app called “Quartz Debug” (drag it to your / Applications/folder if you will use it often).
