Houston We have a problem!!! (737NG)

Pentium4 2.6gig 800mhz FSB (Dell 8300)ATI Radeon9700proWindowsXP Home1gig SDRAM100gig HDFrame rates are a problem after using this plane for awhile (this is only when I choose the rear cabin option or use the 2D panel in a turn). I notice that the plane seems to need allot more thrust coming in for landings than it should, reverse thrust is not strong enough to help stop the plane on landing rolls, and the braking is kind of weak. I had to adjust the AIR file from -20 to -50 to give me more reverse thrust power. At KMDW I would just over shoot the runway when trying to land and end up in the trees. KMDW is a perfect airport to test aircraft such as this (737s), these planes fly in and out of that airport all the time. Overall the plane is underpowered because I can barley take off from KMDW. I tried to adjust my fuel load to 50% fuel in each tank but that did not solve the problem (still testing, I might not have the trim set correctly). I can't use the rear cabin because the frame rate hit is too great on my system or better yet it's noticeable enough to #### me off (machine specs above). I'll try and post more findings as I see them....P.S. After writing this I saw there is an *Issues* thread. Now I'm trying to figure out out to delete this post since I posted the same thing over in the other thread...
