I'm 100% positive I've seen this with airplanes other than ours (seems like it happens more with ATI cards to me, I remember seeing it years ago with my 4870, I don't see it now on my GTX570) - it's not a PMDG bug, it's an FSX graphics engine issue.

Serious issue or not... this is something I've noticed now and then in FSX for years. Sometimes it's fixed by (or occurs when) leaving/entering fullscreen or the menu bar. My guess is that it's some kind of memory management bug within FSX. The reason you haven't seen it before could be that the 737NGX really needs a lot of memory/resources and that this causes the bug to be triggered (just guessing here). Anyway I really doubt that PMDG is able to fix the root cause of this issue.

Could have something to do with controller gauges in the VC that are set to 0,0 position and are often the size of 1x1 pixel or with the way AA works in FSX on ATI cards. I'm seeing this too (ATI card) but i don't mind.

We absolutely are not able to, we have zero control over the FSX graphics engine, memory, or what the video driver is doing.

Like I said, positive I've seen this on other non-PMDG aircraft too. I've seen it going down the sides of the screen too, not just at the top.

I am on an ATi card as well and have some little artifacts as well. It doesn't bother me, but the OP seems to be a perfectionist.

I have never seen this on any PMDG plane and I have the 747-MD11 and NGX. Course I have always used Nvidia cards and have read hundreds of threads about ATI vs Nvidia on FSX. In all of them the Nvidia Card Owners were experiencing less issues than the ATI Owners. To me this says, ATI and FSX suck!

Must admit I can't see the problem there at all. If it bugs you that much then I would adjust the screen upwards to move it off the screen. G

I just tried and loaded my Tower view airplane, which has zero gauges or model and the effect is still there. So indeed it has nothing to do with PMDG or any other airplane but only ATI or FSX.

I´m still trying to locate the bug!!

Which other airplanes?I've posted screens from two other popular add-ons.I also own Aerosoft Airbus-X, Feelthere Airbus Evolution, Captain 727 and 707, Level-D 767, Flight 1 Super 80 and Cessna T182T, all the Carenado fleet, A2A Cub, Realair Turbine Duke, Lionheart Kodiak, and the Accusim Spitfire.All are clean off the edge.I have many systems, both AMD and Intel, both Radeon and GeForce.So far have ran an Intel Q9550 with an Asus GTX 560 Ti, and a Phenom II X4 965 with an Asus Radeon 5870.Same deal.I have many monitors from old CRT's and small vintage LCD's, up to my new current workhorse the Eizo CG303W 30".The better the monitor, the worse it looks.Surely there must be something that can be fixed here.In the mean time I guess I can mess with monitor settings like Adam suggested, but my Eizo is brand new and set me back 5K, I'm a little spooked to start tweaking it sans color calibration

Ok look, I'm not going to argue with the wise crack comments here.I've been in this as both a hobby since the Sublogic Apple IIe days, and professionally since 1999 working on simulators from government sub contractors on simulator sub systems, all the way up to building a complete successful commercial flightsim facility in 1996-7.I think I know a little bit about the suspension of disbelief business and how important visuals are to that effect.I've had several of my old colleague's including a friend who is an active A320 line pilot over to the house recently to demo the NGX, and all were impressed with the systems modeling, but all pointed out the top edge of the screen as an annoyance as well. I'm now retired and yes as a poster above commented 'I do have a lot of time on my hands' So I've been trying to decide which way to go in setting up a home cockpit, Airbus or Boeing.I have complete hardware panel sets for both, and the NGX could be a viable option to the standard Project Magenta route with an NGX SDK, so yes I'm scrutinizing it.Obviously those that aren't bothered by it are either running on fairly small visual systems with un-calibrated monitors with poor DR, color gamut, laptops, etc, or run so far zoomed out in the VC that the overheads block the effect..Your welcome to meet me at Flightdeck (I'm only 20min away) and I'll bring along a couple large high quality S-IPS monitors and we'll plug em in.Then at cruise altitude we'll bring the staff in and vote how many think its not a serious graphic bug.Its a great simulation, but the rough edges need a little polishing, literally :)

Sigh... are we going to start comparing how long we've been in the hobby and who's monitors are better? As i said (and i have no intention of offending you) i have noticed the artifacts myself, i have noticed them on a lot of the planes i own and fly. Futher note: I have noticed that the artifacts appear less...or not at all in window mode. In response to your earlier question, i have seen similar artifacts in the CS707, CS C130 and the Katana. I really do hope that this doesn't ruin your enjoyment of the simulation. Thanks

I didn't see it at first either. I think he's talking about the little white line at the very top of the screen which is really only noticable at night time when you pan your view from a light colored object to a dark area.I get this as well with the LDS 767 and other a/c as well as in spot or VC view. I can easily fix it by just panning down to a dark are then panning back up. It's like white or light colors get trapped in the last line of pixels on the top of the screen and stay there until you pan down and collect dark pixels to fill it back in. I've had this for years and noticed it a long time ago after updating my nVidia drivers to a newer version.Sean Campbell

Yes I am a perfectionist when it comes to flightsimulators Morse, I got paid for being that :)

Meanwhile, Bob and Janet are sitting at home, having paid $70 for a product they cannot activate, but ouch. Look at that line. I don't know how you survive. How can you even start the engines with that line? Or taxi? Takeoff must be impossible

Yeah i was with you...but after reading the chaps comments i do understand his point this sort of thing can be annoying. But perhaps it would have been better titled as Graphic bug...not the serious part!
