For anyone wondering, the binary version of Unreal is a million times better, at least in my experience.
When I was using the version built from source, performance wise was okay, but anything related to C++ was a pain. Now with the version from Epic I’m creating C++ classes instantly, getting real-time Intellisense and compiling inside of the engine takes no more than 5 seconds.
It’s literally mind blowing how good everything is performing right now. Also don’t forget it’s still in Preview, so things are only going to get better.
Don’t hesitate, download the engine and try it yourself!
