  1. Graphics can be tweaked in the option menu and most features can be turned off to run on any potato.
  2. Better graphics does not mean worse performance. Cryengine runs much faster than UE4 while having tons more graphical features than UE4 has.

Implementing graphical features isn’t just about putting in some code, call it a day and stop supporting it i.e vol fog/lighting. It’s more about continuous try to improve it, making it run better while also looking better.

It is quite realistic to expect every single high end feature to be present in this engine. At current rate, UE4 is in transformation to become “the potato game maker machine” because industry has been moving forward and Epic has been moving side ways.

But Epic has proved to not be in the business of providing production ready/optimized features i.e recent so called physically based lighting addition. So any discussion from GI to physical lights to open world tools to something as simple as spline deals for making roads is quite pointless.

summed it up pretty well.

  1. Is it needed for Fortnite
  2. Is Fortnite needed it
  3. For Fortnite is it needed

Replace Fortnite with whatever their next game is called and you’ll have a clear understanding of how much improvements you’re gonna have to expect.
