For anybody else whom may be experiencing similar problems to me with white flashing texture tiles, I have been playing around for a few days now and using only Water Effects=6 and MaxTextureLoad=30 seems to have erradicated the problem. When I move move slider back two notches for water effects mid flight, the flashing tiles return! Why having a HIGHER water setting should solve the problem, I have no idea but it certainly seems to be working for me at present. Next step is to slowly introduce some other tweaks, one by one and see if it returns or if it is soley down the water settings I have.......

Hi guys,So I've installed FSX as per Nicks guide and flying with no adds at the moment trying to tune my system before adding more complexity.I have the sliders setup as per Nicks recommendations and find I get good smooth flight and can easily acheive 24-30fps when locked at that within FSX over Seattle in the F18.What I'm seeing though are occasional "flashing" texture tiles.....little parts of the scenery which flash to white and then are redrawn as quickly as the dissappear. Sometimes I can go without seeing any for 10-15 seconds and I might then see a few in a couple of seconds....there doesn't seem to be any pattern to it.I also get the clouds doing the same thing except they seem to dissappear completely for a split second and then get redrawn.I have tried turning off the limiter, overclocking the CPU and I've used Bojetes tool to configure my .cfg all to no avail. I've now let FSX rewrite the .cfg and it's stlll exactly the same.Has anyone ever noticed similar behaviour or know what could be causing it? I run a factory OC GTX260 896MB, i7 860 and 4GB 6-8-6-24 at 1600. Does this sound like some kind of graphics corruption? Like I say, OC the CPU to 3.8 had no discernable effect. I did think it may be to do with flying low and fast over dense scenery but even when I slow to 200kts (or indeed when I first rotate from KSEA) I still see the occasional flashing tile.Any help, advice or suggestions would be very much appreciated as I'm going mad trying to tie this down and it's really spoiling what is otherwise a smooth flying experience!
