The in-game stalls and hitches have several causes, one is shader compilation because UE4 is heavily invested and designed around the DX11 shader compilation model which means it performs poorly with DX12/Vulkan/Metal/OpenGL which all have a more explicit model that requires developers do more work to make it efficient. Metal got us to 70-85% and we have been hovering around that ever since. By the time of the closed Alpha weвЂ™d dragged it to more like ~60% of PC, still using OpenGL.

When I started at Epic (2013) the Mac version of Fortnite ran at ~40% of PC using OpenGL. There are dedicated Mac engineers but as with all things there is more work to do than time and people to do it.) (* IвЂ™m an engine team programmer not dedicated to Fortnite so I only spend short spells attacking individual bugs unlike the dedicated game team engineers. months, not hours*) to work on Mac Fortnite - obviously donвЂ™t hold your breath! Maybe now I can get some proper time (i.e. The GPU vendors and Apple are also looking at the performance differential and we are working with them to eliminate it, but it doesnвЂ™t appear to have a single straightforward cause so far which means I canвЂ™t and wonвЂ™t make promises I canвЂ™t keep. I am personally hoping to keep plugging away at Mac/PC differences over the rest of this year as we move to support macOS Mojave and get AppleвЂ™s new tools working with UE4. While you wonвЂ™t see it in the current version of Fortnite there are pretty big changes coming in the UE4 4.20 that should help Mac Fortnite considerably when integrated into the game - I canвЂ™t tell you when as I donвЂ™t know. bringing the desktop-forward, aka VR, renderer to iOS). There wasnвЂ™t the same focus on the macOS version of UE4, never mind Fortnite, during 2017 as we worked on more high-end iOS support (i.e. Even Xbox has lower graphical fidelity than the High and Epic options on macOS/Windows. The macOS version of Fortnite has a different history and considerably different performance and feature set as it is graphically identical to the PC version, whereas the iOS game is understandably a lot simpler graphically. The conference talk concentrated on discussing the work required for the iOS version of the game and was given by someone who worked on the iOS & PC/Console versions but not directly on the macOS version.
