Epic Games' own Unreal Engine 4 graphics engine powers countless games, some of them you're playing are probably powered by UE4 and you might not even know it. PlayerUnknown's Battlegrounds is a UE4-powered game, which is absolutely killing it right now, and so is another Battle Royale game: Fortnite.
Unreal Engine 4 is one of the most, if not the most popular third-party engine on the market with massive games like Paragon, PUBG, and more powered by the engine. Epic Games is now working on optimizations to Unreal Engine 4 for larger maps, the perfect time for UE4 optimization now that Fortnite: Battle Royale is here, and PUBG killing the Steam most-played games chart constantly.
There are some huge changes for the console, with Xbox One and PS4 both receiving massive improvements.
