MD11 Black screen after "ALT" button

Recommended Posts

Guest Collezio

Hello guys, I wanted to congratulate you for the wonderful Add-on !I also wanted to tell you that I have this problem, in practice when they are full screen, but also in windows mode, whether during the flight hit the button "ALT" to open the toolbar and see the map or otherwise,because on opening a new window in FSX, then the screen goes black and I do not see the airplane and will the scenery .. I see everything in black mode that windows in full screen and I have to restart FSX.I always have this problem and fly without opening windows in FSX!This is My PC:CPU: Intel Core 2 Q6700 Moyherboard: ASUS P5E3 Del. Wi-fi DDR3RAM: OCZ 4GB DDR3Graphic: Asus Nvidia 8800GTS 640M driver 180.48 certifiedSO: Vista Home Premium 32bit SP1Solution ?Thnak You !

This sounds like the "OOM" problems some of us have when switching from full screen to windowed mode. It seems to coincide with times when the Virtual Size of FSX is approaching or above 2Gb as reported by Sysinternals. But whether or not this is coincidence, nobody out here seems to know and PMDG have stayed silent.So far as I am aware, it is a problem unique to PMDG products. But PMDG has said nothing about it. Given that it only happens with PMDG products, my own suspicion is that something in the PMDG models is causing a memory leak, or a conflict with DX9, but that's just a hunch. People have found a variety of solutions, such as turning down/off scenery options etc to reduce the memory load. I've tried everything I can think of and nothing works for me. For me, the only work-around is to avoid switching from full screen to windowed mode. Even then, I am not confident that I could avoid a black screen in a long flight; and I am in fact quite likely to get a black "preview" screen when I've finished the flight and gone back to the FSX opening screen.Tim

I with my PC I have no problems OOM, is only one problem I have with me the MD11 in DX9. I noticed that using DX10 is not the problem, but I have other strange problems with the MD11 aircraft lights.Strange but nobody says anything ...

I get the same symptoms as you describe, with no OOM error messages. It may have nothing to do with memory: nobody around here really seems to know what the matter is. Tim

I recently got the MD-11 and am experiencing this issue, too. It is not just when Alt-Tabbing to another program (such as to the PMDG Load Manager), but can happen anytime I exit the DX view, such as when going back to FSX to change weather or to load a panel state from the PMDG Add On menu. It does not happen every time, but probably at least 1/3 of the time, and the only way to recover is to restart the flight from a save point.The first time I had the problem I searched here and read the speculation that the cause could be OOM errors, so I upgraded to 4Gb, which paid terrific dividends in terms of overall performance but did nothing to aleviate the blank screen problem. So, are there any other ideas for what might be causing this and what might be done about it? Something in this thread suggested it might be a DX9 issue - does anybody have more info on this?Thanks,Mitchell

It unfortunately when performing any operations in FSX. But it is possible that none of PMDG Team responding? I have several add-on aircraft and the problem ce I only with the MD11! I have a problem with the B1900, I do not see the fuselage but I see only the panel!But that is not native to FSX.

This has been an issue for years, with FS9 too.Much speculation, many proposed solutions, I have yet to see it resolved.Only way to really avoid it is (a) do not alt tab (:( do not switch to windowed mode or vice versa © do not go into the FSC config options while in the the 3d world.

Hi,the problem you describe is a known Nvidia graphics driver issue. As mentioned in the Nvidia manuals, using the "ALT" button to leave FSX doesn

"Alt+Tab" is not the same as "Alt+Enter". Nvidia drivers have a problem with the former, but NOT the latter - at least, so far as anyone has ever suggested before. And besides, this problem only occurs with PMDG models. Tim

I've posted before in other threads about this problem and the cure: Set LOD range to medium, in display settings. The problem might have something to do with a limit on polygon count that can be processed/textured. My thoughts: The round FSX earth is build from polygons and setting a high LOD range in combination with a aircraft like MD-11 (extreme high polygon counts in VC and maybe model too) is simply too much to process for some systems.Anyway, LOD range to medium cured the problem completely for me.Regards, Gerrit

I've been having this problem in Vista 64 with 4GB of RAM on a fresh install of the OS and FSX. So far, it's only happened with the MD-11. I get corrupted graphics followed pretty much immediately by a black screen. It is triggered by a task switch or a switch out of full screen graphics. Even loading menus can cause it, as loading the fspassengers map or the PMDG options menu. The graphics get stuck and drag, and then the screen turns black.Pressing Ctrl-C or ESC will bring up the dialog box, but the screen remains black underneath.This is a fresh install of Vista 64 with fresh FSX and MD-11. Comp Specs:Intel E8400 @4ghz (tried at default 3ghz to rule out overclocking issue, no difference)MSI P35D3 Platinum MB4GB DDR3 1066 RAMPNY nvidia 8800 GT 512 with latest drivers (180.42 I believe)Creative Audigy 4Various hard drivesThe problem is reproducible every flight but I can't say which time I go into the menu or hit alt-enter will trigger it.-stefan

Those are exactly the same as the symptoms I get. Still no solution. And no response from PMDG, either. Tim

Post your system specs and maybe we can find a common thread or something that is the root cause of this.-stefan

If you both have the same nVidia drivers (180.42), try rolling back to prior drivers. I don't have an nVidia but I remember at least two others having problems with the 180.xx drivers.I also have Vista64 4GB ram but cannot reproduce your problem on my system. I use an ATI4870 video card, which has its own quircks to be sure. None of them seem bullet proof.

Can someone who isn't having this problem with a comparable system (at least vista 64 and hopefully a GeForce 8000 series card) post what driver revision they are using, or other steps that have been successful? I haven't tried the LOD fix yet, but if that works, I can just use a lower LOD for the MD-11 I suppose.-stefan

I've tried the LOD fix (switching LOD to medium) and can state with certainty that it didn't fix the problem. I opened up the PMDG options menu (in full screen mode) while airborne, and there went my graphics.Can anyone confirm a driver revision where this *doesn't* happen? I can't fly the plane as it is now unless I make absolutely sure I don't need to go into any menus or hit alt-enter to go into another program. So it's basically unusable.I'm yet to reproduce the problem with any aircraft other than the PMDG MD-11.-stefan

Updating again, even though I seem to be the only one paying attention to this:I changed to the 178 drivers. I got further in the flight, but still had the issue.I noticed this time (and one other time) that ground textures stop loading and become a solid light blue shortly before the problem happens. I'm not overclocking the video card, and I've verified that my CPU overclock is unlikely to be the issue by both experiencing the problem with it disabled and also being able to run CPU torture test for several days on end, so it's stable.Is it possible that I just have a bad video card maybe? Although, I still have only had the problem with the PMDG MD-11.-stefan

Ok, I have ruled out video card and driver issues. I put my Radeon X1900XTX card back in and experienced the exact same issue. In flight, switching to the PMDG option menu (or any other menu) kills the graphics.I'm still looking for a workaround here. I'm guessing that FS is just overloaded, but I'm unclear how to fix it. Again, this only happens with the MD-11. Any help from PMDG here would be fantastic.-stefan

Then I recommend you email PMDG support with the specifics of your problem. This seems to be limited to a few users and therefore could be something unique to a few systems. I assume if the problem was understood then an answer would have been posted by now... also, make sure you get an automated response when you email them, their email filtering kinda sucks and you might need to open a google mail account to get through. Good luck, and truly wish I could help but I'm not much of a techie and have not had the problem you are having.

Hi folks,I have the same problems with the MD-11 when running in fullscreen mode. I can avoid the issues described here by running FSX in windowed mode.BUT: in windowed mode I get another problem, which seems to be related:When travelling to bigger airports (KLAX for example), it happens quite frequently that some scenery objects like airport buildings are not displayed any more (i.e. the jetways are standing all on their own). Moving the scenery sliders to the right increases the likehood that this issue shows up. Also the duration of the flight seems to have an influence (longer flights nearly always result in this problem).Now, when the scenery objects are displayed fine, I can switch between windowed and fullscreen mode without any problems. But when I got this scenery object issue, switching between windowed and fullscreen mode (or for example looking at the map when in fullscreen) results in corrupted graphics or a black screen.These things are not restricted to the PMDG MD-11. I recently got the Eaglesoft Cessna Citation II and guess what: same problem (I have posted this in the Eaglesoft Support Forum as well, but no solution yet available).Further, I have tried to reproduce the problem with other aircraft (Aerosoft TwinOtter, Wilco Airbus), but with no success (even with the highest possible scenery settings and FSX being more like a slideshow).Reducing LOD does not help for me as well. I also did some tests to see if the issues are related to memory consumption of the FSX application, but I managed to get FSX running with other aircraft using nearly 3 GB of virtual memory without any problems. The MD-11 starts causing issues at about 2.5 GB virtual memory consumption.So it looks like some aircraft can deal better with higher overall system load, and some can't. Unfortunately the MD-11 seems to belong to the second category.Maybe the upcoming SP for the MD-11 will help here. Hopefully, since from my point of view it is one of the best addons ever created for FSX!But maybe I am totally wrong and the source of these problems is something completely different. So any more ideas will be highly appreciated :( My system:FSX & AccelerationVista 64bit8 GB RAMIntel Q9650 processorGraphics card: ATI HD 4870 (so these problems are not restricted to Nvidia cards)Latest drivers and updates for everything.Thanks & regards, Hans
