Need help on ATI GRAPHIC 5870 and Catalyst



What do I do with the setting on Cayalyst . Should i set to application on AA, AAF, .
Which should i take for AI, AAMODE (, MIPMAP. And which AA should i take.
I am using 8.66 driver on sep 21.
I have graphic problem, when using overdrive even little . I get black line during one of dual monitor on anytime I do something and get squared pixel on crysis warhead everywhere. I still get black cutscene on resident evil 5, if i turned off AA, i get abnormal graphic on some maps.

When i testing mirror edge, i don't much get high FPS on 1920x 1080 resolution i set up to highest setting and 4x AA.
