I moved everything to my SSD, and I magically got the times everybody mentions: initial compile less than 25 minutes, hot recompile ranging from 10 to 30 seconds. It’s probably worth investing in a SSD which I can devote to data, as my current SSD is OS-only and too small to contain Unreal on top of that.
The “faster recompile trick”, however, doesn’t do a lot for me. It doesnt matter whether I put it in the ModuleRules or not, compile always takes between 10 to 30 seconds.
