Just decided to try out Fornite on my i9 32gb 1tb on MacOs just to see how it runs and the results are not good. Without anything else running in the background I can't even get the game to run stable at any framerate (30/60/120) and/or at any resolution (all the way down to 1280) with low settings.
One thing that also bothers me is that it seems to load a very long time and ends up skipping the initial lobby area. Don't know if this is normal, but it just seems to hang at 95% loading, up until a minute or 2 later it shows you jumping.
If anybody can test this game and can check the results/post the settings I'd greatly appreciate it
Did you download the update Apple pushed yesterday? I saw a video for iPhonedo claiming that no issues with Fortnite after the update.
