I need your help, guys!I have just bought a new quite powerful rig (Athlon 4400+ with ATI X1800XL card).When on the ground at some airports I am experiencing strange looking flickering artifacts/spikes which extend from the ground/horizon and fill up part or sometimes the whole of the sky. They flicker for less than a second (that's why I cannot take a screenshot) and from what I could gather appear mainly but not exclusively at airports with detailed payware scenery and appear when I pan around in VC and spot view. The artifcats look like some sort of messed-up building and tree textures and flicker for maybe 1/10th of second.With my previous computer (a humble P4 2.6Mhz with Nvidia Geforce FX5900)never had these problems.Any ideas?Roland

Do you by any chance have a VIA-based motherboard chipset?

Yes I do. The reason I've bought the new quite expensive rig was purely to be able to run FS9 with acceptable frame rates. Please don't tell me bad news, please !

I would start by trying different video drivers. Not necessarily newer but different. Did you build your new system or buy it bundled? It sounds nice. R-

First off, you really should have gotten an Nvidia nForce 4 based motherboard - they're way better than anything with a VIA chipset on it. I've had nothing but problems with VIA chipsets over the years, whereas my last two have been nForce and completely stellar. If you're able to swap whatever board you got out for something like the new ASUS A8N32, do it.But aside from that, here's some things to try:1. Get the latest VIA 4-in-1 driver here:http://www.viaarena.com/default.aspx?PageI...ID=1&CatID=10702. Get the latest ATI Catalyst drivers here:https://support.ati.com/ics/support/default...&questionID=640

Sorry, but I was in a hurry. My wife wants me to assist her cooking new years eve dinner..........My previous PC had a VIA motherboard. My new one in fact has a Nvidia NForce 4 based one and I am running the latest ATi 5.13 driver.Hopefully there is a solution.Roland

Ah that's a good then!Latest nForce driver? (6.70)What kind of options are you setting for the vid card?

turn of adaptive anti aliasing, if you are indeed using that. it gave me problems like that as well

Alex, you were right, many thanks!I had adaptive AA turned on and after having it turned off the problem seems to be gone. Fingers crossed !Roland

Hi RolandI was going to tell you about the AAA because I experience it too. What I wish to add is that I have decided based on my flying to leave it on because the artifacts only seem to happen around some airports and the results of using AAA are just too good to give up.You will decide based on your own flying, but I suggest leaving it on for awhile to see if it is happening enough for you to give up the noticeable improvement.CheersPaul Dahlen

PaulI was actually thinking along similar lines but my favourite home base is KPVD of Flightzone's Rhode Island scenery and that's an airport where the artifcats are real real bad. Same holds true for all add-on Florida airports I've installed whereas at KLAX using Jetways and Terminals scenery with AI maxed at 100% I experience no artifacts at all. Strange isn't it, and outside the US I still have to encounter those artifcats with AAA enabled.In hindsight I should have bought the Geforce 7900GTX and not an ATi card cause I was quite happy running my previous card a weakish Geforce 5900.BTW, could you please let me know what other CCC settings you guys are using, especially AA and vertical refresh? Do you have Catalyst AI switched on or not?Roland

I hope anyone still reads this.I have the same problem but my system is a FX55 with a 6800GT.Not sure if this card has adaptative AA, but if so, this should be what is bothering me. Any idea how to disable it?Thanks,Leo

> but my favourite home base is KPVD of Flightzone's Rhode IslandWhen I built my new machine below, I TOO had the same types of artifacting at KPVD - it is also my home base! (I'm a local) ... big blocks of bad textures, delays when populating textures, etc. etc.Turns out the problem was my video drivers - I was using a slightly older nVidia driver that probably wasn't quite ready for my slightly newer (6800GS) card. I actually performed a full fledged Windows re-install (hadn't loaded anything else except MSFS!) with the current WHQL certified driver, and it worked flawlessly. I would take the driver path first. You may have a bad video card, but I tend to doubt it. -Greg

Yes. This was weird, but going back to the 77.76 driver stopped the flickering. All forcewares above this one keep producing the annoying flickering.Leo
