Ground texture problems FS2002/FS9

Hello!I know I have asked about this before, but til now I haven'tgot any satisfactory tips or help.My FS 2002/ FS9 ground textures pop out of focus every now and then,which gives a rather ridiculous impression.I have tried a lot of different settings, upgraded my PC with a newvideo card, new HDD's, etc. but that doesn't seem to help;the problem remains.Has anyone managed to find ways to remedy this?If so, I would almost be willing to pay for advice.........I am sure my system is OK (P4 2.53 gHz, Radeon 9800 PRO)Thanks!Hans HermanssonSweden
