I'm inclined to agree, but we're starting to hit the zone where I feel I'm using a tool of questionable qualities because of lock-in and the absence of sane competitors. The Unreal Engine IDE runs at 10 fps on my current-gen iMac, an expensive machine based on 2010's hardware and no upgradeable parts that takes minutes to boot up into an increasingly DRM-plagued OS where all the innovation goes into iOS-like features I don't use.

I disagree vehemently that this is what's going on. If that was the "problem", my (software) complaints would not exist.

I'm in a very similar situation with a 2013 iMac and UE4. Particularly when using any serious amounts of DebugDraw (such as when the EQS Testing Pawn is used) the performance drops like a stone. I'd get a new Mac, but there's nothing worth paying for, so I'll probably end up trying to get pci-passthrough working with a Windows VM on a Linux base machine.
