I managed to boot up d4… and get into the loading screens. had my task manager open… and watched d4 use 2 gigs… 4…5… 6… till it used every single bit of ram I had and my computer hard locked.
Is this horribly optimized or is the requirements to have like 32 gigs…

I have 32Gig of Ram, and Diablo 4 just crashed as it ran out of system memory! 
I have 128GB RAM and D4 seems to only use 31.5GB total throughout the game. This definitely will be fixed when the production version is released.
