Well, that's Epic...the creators of Unreal Engine. They know optimization.Sometimes I wonder if PlayerUnknown has a secret skunkworks project to rebuild the whole game on a stable tech foundation. That Fortnight was able to come out and implement a pretty solid Battle Royale in short order should give the PUBG devs a lot of anxiety.
Bluehole, well, clearly does not and it shows both in terms of performance and visual quality. PUBG looks ancient and awful.
