I am very excited to see the Unreal Editor finally come to OS X. I just downloaded to give it a try and was quickly disappointed by the performance. Don’t get me wrong, I’m not complaining here, just giving feedback and I understand that the “Mac OS X support hasn’t undergone serious developer testing yet”.
During my tests, I didn’t get more than 20 fps with any of the example projects. Not even with the simplest ones (Tappy Chicken). I also realized that this doesn’t seem to be a rendering performance issue, because it’s not just the game view that is slow, but the entire editor, including sliders, buttons, scrollers etc.
To rule out that my machine was too slow to handle the load, I also installed the editor on Windows (same machine). On Windows the editor runs smoothly. I get 60 fps for the simpler projects and even on the more complex ones I get a usable 30.
I was/am intending to work on some mobile games and it would be nice, if I could stay on the OS where I am at “home”. I certainly would expect a relatively fast laptop to be able to handle mobile quality graphics, even with the added editor overhead. Thanks for the otherwise very nice work so far!
