Which of the two games requires more power on the PC? Pubg or Fortnite?
Would say now Pubg, but of course also depends on the graphics settings.
Pubg does not need more power with pc but with smartphones
PUBG and that clearly.
Although both games are based on the same engine, Fortnite has some key advantages. On the one hand, the developer Epic is also developer of the Unreal Engine. Say: No one else on the market knows so well about the technology, knows its limits and knows how to handle special tricks. This allows extensive optimizations. And if something does not fit, the engine is simply rewritten accordingly.
Add to that the deliberately chosen graphic style. The cartoon look works with a few details, which requires much less complex models, textures, physics, etc., and thus costs less computing power.
The bottom line is that you can play Fortnite even on systems where PUBG is practically unplayable.
