ATI Catalyst - Help! why does using Super-Sampling AA cause controller lag?

[Celtic Pharaoh]

Hi there. I don't know why this is but when I use Super-Sampling AA, it causes controller lag. I've checked my FPS with Fraps to see if thats the problem but I'm holding above 130+ FPS so why should I have controller lag? Thanks.

What do you have in the Flip Queue Size ???
Try 2 or 3
