I never could solve the wretched CTDs that used occur at random times during FS9 sessions.I needed an upgrade anyway, and I had begun to suspect a hardware problem anyway.So here's the latest specs:A switch to AMD 64 Athlon 2.0G1 G DDRx2 RamGeForce FX 5700 256 Ram by BFGSoundblaster Audigy8x AGP Gigabyte K8 Triton moboWindows XP Home Service Pak 2OK, the deal now is I'm having splotches and spikes flash at times when I'm in the game, and they also happen in the window that displays the aircraft chosen in the "create a flight" page.I tried filling the sky with multi leveled cloud types, and when flying south out of KMKE along the Lake Michigan shoreline, the clouds, outliined in a box, took the place of the lake?!So either this is a video driver issue, or a bug native to FS9.I have installed the FS9 patch.So what do you all think? Anybody know where the specific driver version being used is identified?Thanks!!Glad to be back after a few several months absent!Rick

Start-Run-DXDiagUnder the Display tab, you'll find all the info.The last 4 digits of the display driver is what you are after.BTW, are you overclocking the video card at all?Display artifacts is often a sign of the video card running too hot, or too fast..

Thanks Bert.OK, last 4 digits in the DxDiag report is 7772. So I assume those are the Nvidia 77.72 driver set.With regard to the video card, no it's not overclocked. It's actually about 6 months old, and clean. I don't know how it could be running too hot. Maybe a faulty fan.My computer guru said that specific card wasn't on the market too long due to some stability issues. I'll have to check and see if there is an update somewhere. But perhaps changing the driver set will help.Rick

You can try different drivers... or bring back the card for a replacement. I've had a card go bad on me and had it replaced under warranty (likely 12 months..)
