I finally loaded up DX 9 under my 98SE O/S--not an easy task when you have a dial-up modem. Anyway (and just as Paul has pointed out and I expected), I saw no impact on my system, good or bad. I already thought FS was churning out fairly decent framerates. But DX 9 probably doesn't have any code that'd interest my old GeF/2, other than an odd optimization here or there... I was happy that my Hardware T&L tweak to my 2k2 config was not influenced by the update.... I'm still cranking out 25fps at Sky Harbor, with everything maxed, other than these exceptions:Res--800x600x32Water Detail&Reflections, OffShadows, OffAI-Off (turning it to 50pct costs only 5,6 fps)Hopefully, my system is ready now for all software which requires DX-9-John

DX9 was really optimized with Win XP, I got about a 6-10 FPS boost when I installed it.

I got more consistent FPS when I installed DX 9.0, which was very nice. :)
