At WWDC today, Apple announced OS X 10.11 El Capitan. The new version of the OS is all about refinements and improvements to how windows are handled by the OS.
With El Capitan, Apple has also tuned things at the system level to greatly improve overall performance of the OS. In the company’s tests, El Capitan led to a 1.4x speed improvements in app launch timings, and up to 2x faster switching between apps and displaying of first mail messages. Even opening PDF files in Preview is up to 4x faster on the upcoming version of OS X.
With OS X 10.11, Apple is also bringing Metal to Mac. The graphics technology of Metal will provide developers with “near-direct access” to the GPU to allow them to reduce the overhead from drivers and OpenCL, thereby allowing them to greatly speed up the rendering performance in their apps. Initial updates from Adobe show that OS X 10.11 will bring up to 8x improvements in rendering performance and reduce CPU usage by 2x in certain scenarios.
The final version of OS will be rolled out as a free upgrade everyone this fall, with a public beta version coming in July.
