Hi, It is not so well related with PMDG but anyway I can ask.I upgraded today graphic card from a geforce 2 - 64 GTS to a radeon 9600 pro. Also 2 weeks ago I added more 512 DDR 333 and a processor 2500 XP. Before it was a 2100 XP athlon. Also the motherboard is a newer one.1. FS 2002 runs with less frames, although the system is far better2. FS 2004 tries to load the textures but simply disappears and doesnt load anything any more3. Does it have to do with drivers? FS 2002 seems to run good although with less frames 4. A message saying that the system will shut down like this: Remote procedure called ... NT authorization ... (and something that I have no time to see)Could someone explain what is happening?thankscoimbra

Now, everything is solved but I cannot start FS 2004When tries to load textures disappears ;(hope someone could helpcoimbra

It is strange.How it is possible to have a system 2 times better with half of the frames?Athlon 2100 XP, 512 DDR 333, geforce 2 - 64 MB GTS/PROand nowAthlon 2500 XP, 1024 DDR 333, radeon 9600 PROI am with PMDG aircraft and I have 6 frames at helsinki with FS 2004 and in the same airport with FS 2002, I have 13 ...Any explanation? Some settings must change?I would appreciate helpThanksCoimbra

If you just upgraded from your prior setup then the best you can do is to backup your files an do a complete system format and reinstall, use the most up to date set of drivers for ALL your system devices! I know it's a pain and is hard work, but if you what the best performance from your system this is the ONLY way....Jos

"4. A message saying that the system will shut down like this: Remote procedure called ... NT authorization ... (and something that I have no time to see)"Might want to go to Windows update and download the RPC security patch. Sounds like someone other then you is having fun with your machine.
