    DXGI_ERROR_DEVICE_HUNG error: Is there a solution?

    No, I removed the third GPU of my 3-way SLI attempt. The two left were the ones with the majority of use before in any case. When I was informed (rather belatedly, as I had this since Sept 2017) that 3-way SLI wasn't supported, I re-jigged the SLI links first one way then the other (keeping in common the card with all the displays connected and disabling the disconnected one). This seemed to indicate card 2 but then it happened with 3 also. The fresh defaut setup in NCP was by using DDU and installing a new version of the nVidia driver. I'm not sure the error has really gone yet. I haven't actually tried flying. Pete

    So do you mean that has to be stopped somehow? Some dep -rooted Windows services? Maybe so, but I been testing all day with no recurrence. That would be neat, but it has only ever occurred he in a particular scenery -- but one which I've been using in P3D4, rigorously (after all, it is EGLL) since first installing P3D4 (and before, in previouus scenery versions). Before P3D4.4 is occurred just once, a month or two ago. With P3D 4.4. it just started occurring reproducibly -- but now, not since i installed newer nVidia drivers. Or that something in the Video Driver actions for the 1080 are liable to reveal the error, whilst those for the 2080 are not. Also, of course, you have to consider that you are probably driving the 2080 to a lot less than its performance capacity compared to the 1080. I thought I had it narrowed down to a specific 1080 card (one out of three) but after removing that I got it on one of the others. Pete

    DXGI_ERROR_DEVICE_HUNG error: Is there a solution?

    No. Other processes are running, of course, but the focus is on the P3D display across the three projectors. In NCP you mean? Why create a profile at all? I've never used one and have only been getting these DXGI errors recently (with 4.4 really -- just once before 4.4, since installing P3D4 on this system 18 months ago!). No browser use at all on the P3D4 PC. It is dedicated to the cockpit only. I cannot easily use other programs on the curved 210 FOV screen -- most of the time, with my RP narrow vision, I can't even find the mouse pointer. To set things up (whether NCP or other) I have to use TeamViewer from another PC. In dense situations I am doing well if it reaches 20 fps! I'd be over the moon if it never dropped below 30 (which is effectively my limit in any case, via VSync and Projectors set to 30Hz)! Pete

    Not sure whether a static voltage test, without the PSU being under load, tells you much. It's whether it can sustain them under load. Can those values be displayed at such times? Incidentally, my DXGI problem probably isn't GPU related as it can happen with either of two cards. I suppose it could be PSU related, but I'm still more inclined to think it is in the area of P3D/Windows/nVidia. So far it hasn't happened since cleaning the video driver with DDU and installing the latest (471.22, at least the latest a couple of days ago). But then I haven't had time to do a lot of testing.

    DXGI_ERROR_DEVICE_HUNG error: Is there a solution?

    Yes, I did that a while ago, when I first saw this tip. I had already set it as a DWORD, to o avail, then to a QWORD when I saw the later suggestion. It should still be s't somehow reverted. Thanks, is a fancy page with a menu starting with "Platforms". Of the top menu the most likely I thought was either "Drivers" or "Support",. Both lead to lots of other links, but none prove relevant to SLI. Yes, I already know that it only occurs when I'm heavily loading the graphics / P3D. It occurs at EGLL with traffic, and is most likely at dusk or night (night has always been a terrible performer for me. Don't know why when most of the scenery is blacked out). But the point is that I never used to have the DXGI problems and I've been using the same scenery for a long time (UK2000 or Aerosoft EGLL). Both are the most testing places I've got, which is why I use them for testing! If everything is okay there I then know it will be okay everywhere else. Pete

    FSPS - FFTF Dynamic for P3Dv4 (update v4.4)

    I think you have to use the menu item to check for new versions. i don't think it automatically looks. Pete

    DXGI_ERROR_DEVICE_HUNG error: Is there a solution?

    I didn't know that. I'll take a look. Thanks. [LATER] Can't seem to find it. Have you a link or a clue, please? Wouldn't they have built this patch into the newer drivers by now? Pete

    DXGI_ERROR_DEVICE_HUNG error: Is there a solution?

    Yes, I see all that. But why make myself a profile if the PC is only ever used for P3D4, and I'm happily setting the main settings, not needing a profile? I thought you were implying that P3D or nVidia came with a profile for P3D. I can of course just make a change and save, but I've no need for a specific profile. and I have made changes. I tend to check things and set them again after each clean driver install or update. Pete

    Old tweak still to be used in P3Dv4.4 ?

    No. I just use VSync in P3D. My projectors are all 30Hz. works fine. Frame Rate limiter is set to unlimited. Pete

    DXGI_ERROR_DEVICE_HUNG error: Is there a solution?

    Okay. Not today though. Finished for the day. I cleaned up the video driver stuff with DDU and installed 471.22. Oddly, after that I couldn't set the refresh rate on 2 out of 3 of my projectors to 30 Hz. Below 60 it only offered 50, 25 and lower -- but only on those two (all three are identical Acer projectors)! So re-booted (again), Then I was offered 29 on those, no 30. so now all three are set to 29Hz instead of 30 as before! Weird. Anyway, in exactly the same scenario as before -- same place, same time, it was okay. I'm not (yet) assuming the driver tidy & update helped here, so next time I go into one of these high demand scenerios, I'll first enable GPUZ logging. Thanks, Pete

    I do too! And now FFTF.EXE is released for 4.4 I've got that going down to 0.01 when my frame rates are struggling (below 20). Pete

    DXGI_ERROR_DEVICE_HUNG error: Is there a solution?

    How, please? What do I need to use? GPU-Z or Afterburner? Did that when looking at removing the middle card of the original 3-way SLI arrangement. It wasn't so easy to do that. Cooling cables all over the place, linking each card to a separate fine on the perimeters of the case. To get the card out I'd have to do a lot more than I anticipated, so all i did was remove the now defunct SLI links and ensure the card was disabled in Device Manager. Pete

    FSUIPC AI limiter in 4.4

    FSUIPC merely deletes AI aircraft when there are more than your limit. There's no magic involved. I cannot stop them being generated. It is working fine here with P3D4.4. I can't imagine how it can not delete aircraft, really. It's calling a regular exported P3D function to do the deletions. Pete

    DXGI_ERROR_DEVICE_HUNG error: Is there a solution?

    Well, after a couple of days without the dreaded DXGI device hung error, I just got one -- immediately when going to EGLL (my heaviest loading airport). It didn't even get time to display! This is with the less used GPU disabled. So I don't think that video card is faulty. I've no idea what is going on, nor what to try next. These errors are all recent, infrequently with P3D4.3 but now a real stopper with 4.4. I've had this system nearly 18 months now, so something else software related is wrong. I'll try using DDU to clean up this video driver, and install the latest. Pete
