1 Stutter on Flare

Hi:I was getting 1 stutter on flaring in big airports such as Sea-Tac. Based on a member's post, I reduced textures to one notch below massive. Sure enough, no more stutters. I was wondering if anyone has found a way to do away with stutters, but still keep the massive textures which make the big hubs look so good. My specs: fx55, 1 gig 3200 duel, x800xt 256. Agp Ap at 128, all latencies at 64 or below.Thanks
