We have switched the Mac renderer from OpenGL to MoltenVK (Metal) to support the upcoming release of the upcoming MacOS Mojave. Upon first launching the game, you will notice longer load times and frequent hitching as the shaders are rebuilt for MoltenVK, with some notable unstableness in this first PTS patch. We plan to make iterations throughout PTS to improve performance. To support these changes, we will be updating the minimum spec for all Mac players in Update 20. These will be as follows:
Operating System: macOS High Sierra v 10.13
Model: Late-2013 27-inch iMac and Newer
