FS9 better on Dual PIII than FS2K2

Has M$ added SMP ( Dual CPU ) support in FS9 ? I am consistly over 25 FPS with all sliders maxed ( including traffic ) except clouds/autogen, and a 1600x1200x32 res with real weather. I was all ready to invest in a new system and I found that FS9 is actually working like a charm on my current system while FS2K2 was struggling - both in their native form ( no add-ons ).The performance goes down to 10-15 FPS when there is a heavy low ceiling/overcast. I will most likely take a hit when I add heavy AI traffic using ttools and third party airports.Here are my specs:HP Kayak XM600 Dual 1 Ghz CPUs. 1Gig Rambus PC800, 73 Gig 15K SCSI, 32M GeForce2 GTS ( latest drivers ) + Win XP Pro + DirectX 9a.NVidia settings: Image=Performance, Antialias=4x, Anisotropic=off
