At 51 years old I finally decided to build my own box and now it's done, BUT I'm getting some seriously annoying autogen artifacts when flying near cities - colored lines flashing full screen (but only one monitor at a time), buildings flashing in and out, geometric polygons, etc., and I can't figure out what the problem is.It seems to be worse when clouds load from ActiveSky 6.5 and Flight Environment -- using low res clouds for now from FE, do not use ASG at all. I have UT USA and Canada, with the UT Cities and FSGenesis patch properly installed and ordered in the scenery library. I have switched out all hardware one at a time to test that it's all working and still no joy correcting the problem. Sim runs smoothly otherwise with 30 - 40 FPS no prob, and I thought at first it may be a problem with Flight Environment/Bird's Eye View Autogen/and Ultimate Terrain, but it all played very nicely with no problems whatsoever on my Dell Dimension E520 and it only had an E6520 processor and x1950 Pro Vid Card. BTW, my video card is new -- I just bought it Sunday to test hardware, and even that didn't help. I've tried the latest drivers and some on the ATI site from December and April, 2007. I tried loading my old nVidia card to check it on that, but I got so frustrated at that point with the the nHancer/AA tweaking I just gave up.I've even done a fresh FS9 install and then after that, used an Acronis image from a known good install, and after all that the only thing that seemed to me to offer any help was the just moving the autogen slider full right. CPU temp is low 30s C.Would anyone be able to provide me with some additional guidance or help? I'll try just about anything at this point. I can't go back now, and my wife is bugging to see more of me than my rear sticking our from under my computer desk. ;-)As always, thank you in advance -- I tried to keep this post as short as possible.

Did I see the Power Supply in the sig? Should be item the #1 item, in Bold. If all else fails . . .

Thanks, Sam. I can't recall the brand off hand -- I'm in my office. It's over 600 watts, which should be plenty.

Sounds like a no-name that came with the case. Don't trust it.

No, I bought it separately -- I just am not that conversant in Power Supplies and I can't remember right now.

You're getting visual artifacting? I'd say power supply or heat on the vid card.How's your Direct3D install? I've seen corrupted D3D installations do strange things, too.RhettE8500, Arctic Cooling Freezer 7 Pro, ASUS P5E3 Premium, BFG 8800GTX 756 (nVidia 169 WHQL), 4gb DDR3 1600 Patriot Cas7 7-7-7-20 (2T), PC Power 750, WD 150gb 10000rpm Raptor, Seagate 500gb, Silverstone TJ09 case, Vista Ultimate 64

Direct3D. Hmmmmmmmmmmmm.

#1 Could be power supply Could be Heat Could be drivers Could be bad cardJust noticed you are running an OC'd video card. I had a problem once where I had to turn down the speeds on my video card to cure the same issue. Can you underclock it?ANDYou are limiting yourself with your memory. Look at what I am doing with a similar setup and some DDR3...You are driving a V-8 with 2 blown cylinders ;)-PPrimary RigLiquid CooledIntel C2D E8500 468X9.5 @ 4.45Asus Maximus Extreme2 gigs OCZ Reaper DDR3 @1400Dual OC'd XFX 8800GTX @ 2 gigs24 inch Widescreen LCD 16XAA/16XAFDual 19 inch LCD'sRaid-0+1 + single SATA 3Gbp/s Swap drivePCPower and Cooling 1k Quad SLIhttp://home.comcast.net/~psolk/3monitorsa.htmlBackup RigAMD 4000 San Diego @ 2.72 Gigs Kingston Corsair XMS CL2XFX 7900 GTX Raid-0

Chuck, make sure "Force Mip-Map Filter" is not enabled. The autogen artifacting you mention sounds like what one sees when forcing the mip-map filter.

Greg:Where is that filter? In the ATI CCC Manager, or FS9 itself? Thanks, I'm having a senior moment.I've tried everything suggested here, plus updating my BIOS and DirectX -- still no joy. Also, I went to BestBuy and got a 700 Watt RocketFish (BestBuy brand!) Power Supply -- it was the biggest one they had. If that helps, then I know that's where the problem is and I'll order a better one from TigerDirect or NewEgg. I'll post how that turns out here tomorrow after work. Can anyone think of anything else to try? Thanks everyone for your suggestions. I haven't given up.

Where is that filter? In the ATI CCC Manager, or FS9 itself?It's in CCC. It's a D3D setting (sorry I can't say where exactly... I haven't used CCC in quite a while).Cheers,

OK, folks, I'm pretty sure it's the mip-map settings as Greg suggested -- but I need a little more time testing. I put in the new power supply this morning before work, absolutely no change -- same splashy artifacts and messed up autogen. Thanks again, Greg.When I went into ATI's CCC Manager and slid the Mip Map Settings slider all the way to the left from "Quality" to the "Performance" setting, all artifacts cleared right up. During a test flight, I then paused FS9, opened CCC Manger, slid it all the way to the right back to the full "Quality" setting and Bang! -- all the artifacts and colorful lines popped right back up on the screen in front of my eyes! BUT, there did appear to be a significant degradation of detail, most notably in roads that appeared to now be made up of visible little squares instead of the smooth sided gray (ugly) roads I usually get in FS2004.AND, to top it off, there appears to be no setting in the ATI CCC Manager to completely shut Mip Maps off, like nHancer has. Does anyone know where I would do this?What I don't understand is why this setting is a problem on my new system, which is a better processor, MB, etc., and has not been a problem with the two lesser systems before it??? With and without the same video cards!Thanks to everyone who helped up to now, it seems I can at least now see the light at the end of the tunnel -- you've all given me a lot to think about -- new power supply, better ram, more research on Mip Maps. I just hope I can get it all done in the next 30 or 40 years before I die. :-)

When I went into ATI's CCC Manager and slid the Mip Map Settings slider all the way to the left from "Quality" to the "Performance" setting, all artifacts cleared right up.This would seem to indicate that the problem is with CCC holding changes to the drivers configuration in your system's registry. You might want to try the latest version of ATI Tray Tools: http://cid-a50350ea7a969f0c.skydrive.live....ic/attsetup.exeThe "Force Mip-Map Filter" setting is found by clicking: Tweaks>Standard Tweaks. The "Force Mip-Map Filter" box should be unchecked.Good luck,

Thanks again Greg! I found that today during my research and I'll give it a try after I land at KBOS -- looks like it was the mip map setting. So far so good.Thanks again, everybody, and especially to you, Greg! I wish I'd posted 3 days earlier.

SUCCESS! I just landed at George Grimshaw's detailed KBOS and not an artifact in sight! 22 FPS with AI at 60%, AA at 8x and AF at 16x. I wonder what it'll be like tomorrow after I get my 2 gigs OCZ Reaper DDR3 RAM as suggested above by psolk?!?This is going to be GREAT! Thank you so much for your help, guys!
