With the latest ultra-powerful Qualcomm chip, it’s possible that Unreal may one day develop a version adapted for features like Nanite or Lumen for mobile platforms. For now, Unreal doesn’t seem to be putting much effort into supporting this kind of chip. Unity, on the other hand, seems to be at the cutting edge when it comes to the latest features of these chips. I far prefer Unreal to Unity.
I hope the Unreal developers will be able to respond to me.
