I know its still very early to talk about optimization at this stage, but I do hope its one of the higher priority for the developer and will be done properly when most of the Gameplay element is polished out.
UE4 is great for people like me rocking higher end hardware, but its also concerning to me that Developers rely too much on brute force from hardware rather than optimization (cough PUBG cough).
Speaking of PUBG and UE4, I do hope the game isn't like that which uses at MOST 4 cores 4 threads - which sucks for HEDT platform and people like me using Ryzen 6 cores and 8 cores. A game like this is very CPU intensive with lots of physics and destruction, as well as for 100+ FPS gaming.
Anyway, can't wait for Alpha, really hope I get selected
