@ahmed023 I have an i5, 8gb ram, and a Redeon R9 390 8gb. After overclocking I get 50-60 fps on redux with ultra settings at 1080p. I have dialled the grass and water and reflection down a step though because I don't find much need for those. However, if I use the scaling option in the Advanced Graphics settings, my fps drops down to 35-40 at x1.25. Check to see if you've got scaling enabled!
