Whenever i play ,with my new sapphire 5600xt 6GB, WoW in Dungeons or Raids my framerate is at 30fps and as the fight continues the fps drops lower and lower until the screen freezes up to 10s making it unplayable. Even in open world i can not get over 50fps. My old GTX 770 allowed me 120 fps open world. 60fps in-combat.
Is there anything else then waiting for updated Drivers?
