I've installed FS2002 with essentially default setting on a Dell T-600, 600-MHz, 256-SDRAM.
Once fired up, it works acceptably smooth, with frame rates in the vicinity of 20-25. As others have reported, it's silky smooth and very "flyable."
However, in firing up, or in changing a location or even a Time of Day, there's an "i" screen that takes perhaps a minute as it goes through its routine of Loading Scenery, 3D, AI, etc.
This is in marked contrast to my FS98 setup (which is crammed with add-on scenery, all activated). There, such changes of Airport or Time of Day are essentially instantaneous.
I suspect that deactivating the unused scenery would help. And, of course, I sense that a 600-MHz machine is old hat these days. But are there other ways to shorten this loading time?
Thanks in advance. -- Dennis S, FSEngEd@aol.com
