RE: Other sims capable of doing 5D?
Hmmm...what would one call the "new" flight characteristics and flying in G3? Certainly not VTOL. How about "Bass-ackwards" TOL (BATOL)? Frontal-lobotomy hovering? The "betcha can't do this dippy-flippo"? Heard one pilot hovering nose down remarking, "I'm hangin' by my harness and the chafin' is gettin' out of hand!"
I've got my "stock" card back in my Athlon 64 (I traded in my 6800 GT for a 6800 Ultra PCIe for the new machine) and it doesn't run G3 well at all...it's a pig of a video card (FX-5200). The Ultra won't get here for another week or more, so I'm relegated to harassing flight-sim forum posters...watch out! ;-}
