I thought you were talking about it being resource heavy relative to unity, not to your own home grown one, which is likely (and obviously) much lighter. I have no doubt in that comparison all the larger game engines have quite resource heavy editor. But the tradeoff is supposed to be that few extra seconds loading it up and few GB downloading it, saves you potentially months of work you don’t need to do yourself in a more custom engine.
the 2 minute plugin change also seems really off. I can tweak my plugins and recompile in a few seconds.
Intellisense is much better than it used to, at least on my own machine, but I will admit it was finicky for me for a while. Its usually instant for me nowadays, though I will admit at one point it was ridiculously slow(5-10 seconds). I have no idea what I’ve changed and I am on the same computer.
no getting around UE4 being quite big, several GB, to download.
