I'll give you strange advice, but this definitely works with mine gtx 480 (comparable with gtx 570 card). Find OLD nvidia drivers. In my case it was 260.99. I has only 20 fps with 301 drivers (1920x1200 resolution), it was quite unplayable, especially with high ping and human opponents. Now I've got 50+ fps with high+ settings. In your case starting point is 266.58 whql.
