I have two PC's running FSX Accel. One is XP and one is Vista 64, so it is easy to compare some features side-by-side. Here's one I have not been able to resolve. Here's two examples. Go to KONT, parking 30 Fuel or KBOS, parking 13 Fuel. At Dawn, Day or Dusk the fuel stand is visible, but at night it totally disappears. I have seen some info on various forums about night texture issues, but have not seen this particular problem addressed. In XP this problem does not exist, but does in Vista 64.Vista 64 Home PremiumIntel i7 950 (3.07GHz)9.0 GB DDR3 RAMNVIDIA GeForce GTX285 (1 GB RAM)

Obviously it's system specific, mine is still there in vista 64 bit.

I'm running FSX SP2 on a Vista 64 system. No problem with disappearing objects in DX9 mode. With DX10 preview mode the objects will disappear during the night. Do you run FSX in DX10 mode on your Vista system?

Yes, sorry I forgot to mention. DX10 is one of the features bragged about in running FSX in Vista. Running in DX9 would defeat the advantages.

Then your'e bound to find more differences between your XP DX9 FSX and Vista DX10 FSX setups :(

Yes, but running DX9 would eliminate the DX10 disadvantages. Your choice.
