It's not just the new T-45C; it's happening on all my birds (with/without tail hooks) but only around the boat. I have been running with this system for over a year with good performance, no problems at all. It's strange, it only happens around the boat and I'm fine for two passes and then my third pass turns into a slide show (5-12 FPS). As soon as I "turn off" the carriers I jump right back to 40+ FPS.
I'm running a dual core 2.8 GHZ with 4 gig of RAM with a decent NVIDA card (Dell M4400). Not an ideal rig (my other system died awhile back) but with very conservative settings I've had consistent performance.
Of course the only thing I have time for is a few day, night, and foul weather passes to keep my skills up around the boat.
This system struggles with the VRS Super Bug, but that's expected.
I thought maybe my HD was on the fritz until I got my FPS back after turning the boat off (I do regular defrags); I only use this system for FSX, it hardly ever touches the Internet unless I'm downloading something for FSX.
I guess it's time for a new system; I really want to wait until Fall before buying, I'm just to busy this summer.
I was hoping that someone out there would offer a "oh try this"; I figured someone might have/had similar symptoms.
