Well I think I'm losing it. Everything maxed out, that relates to scenery/textures anyway. I do much flying in BC Canada but other parts of the world when the fancy takes me. I've got some brill scenery of BC by Holger Sandmann which is the best. This problem is by no means particular to that scenery.
At ground level and up to about 4,000 feet the scenery remains good. Climb above that to 10-12,000 and as you might expect you lose definition and clarity of scenery. It's when I come down to land I just seem to lose a great deal of texture definition. Airports and runways are OK. If I tweak settings at about 3000ft all is OK. By tweaking I mean 'drop' down a notch or two which is the opposite to what I thought would happen.
I'm running a 64mb GEForce 5700 Ultra card, 512mb RAM, 2.4 AMD Athlon processor, 60gb hd. I thought my motherboard might be the problem. The card is x8 AGP but my board rating will only take x4 AGP which I've been told should not be a problem. FS2002 runs like a dream. Any comments, suggested tweaks would be gratefully received.
