is Arma 3 poorly optimized?
The game isn't well optimized for your setup, causing low FPS.
Dayz suffers from poor optimization, possibly because it's a standalone game using Arma 3's engine.
Yes.
Their engine lacks good optimization, that's correct.
Sure, I'm here to help. What do you need?

I generally experience extremely low frame rates.
