Short story,had gtx 970,got rx 590,not much fps difference,turned all the shit off in radeon software and ive got significantly better fps now,reason why i bothered to do this is because i never seen anyone talk about EFT radeon settings or anything. Pics are from offline,hope it helps.
online i went from 40-60 to good 60-80
