hi i'm using vegas audio 2.0 d and now i'm workin on a song which has 24 tracks and some of them have Track FX. I have 256 mb ram and an AMD 900 mhz and a SB 128 pci. But it still stuttering!! vegas plays the first 5 seconds nice and than it has to buffer and stuff i guess. i have tried different buffer settings but it doesnt help!

how is this possible??
