In my opinion this is one of the most important things that the devs should be working on.
When I saw the system requirements to play this game I thought I would be able to run the game smoothly at least on the lowest settings but I'm having a hard time trying to play the game with a extremely low FPS.
My computer is not very good but that doesn't explain the 9 FPS I'm experiencing inside Cherno or Elektro. When I run some hardware monitoring programs while running DayZ they show an usage of about only 50% of my GPU, leaving all excess rendering to my processor which is unable to process everything.
I don't mind waiting for months until the performance is improved (it's on alpha after all), but if it doesn't, I'll have wasted my money because I wouldn't have bought the game if the system requirements provided showed I wouldn't be able to run it decently
