PMDG Forum Rules

1) SIGN YOUR POSTS. Since 1997, we have asked users to sign their real name, first and last, to all posts in the PMDG forum. We do this in order to keep conversations personal and familiar. You took the time to be here, we want to get to know you. This is one of the few rigid rules that we enforce regularly. We do so because we feel that forums in which users must engage one another personally are generally warmer, more collegial and friendly. Posts that are unsigned will be quietly removed without comment by the moderators, so to make your life easy- we recommend enabling your forum signature so that you never need to remember. Do this by clicking the username pull-down at the top right, then selecting "User Settings." You will find the signature editor on the ACCOUNT tab, about half way down the page. Look for "Edit Post Signature." Be sure to click the "Show Signatures" box.

2) BE NICE. We are all simmers here and no matter our differences of opinion, we share a common love of aviation, computing and simulation. Treat everyone else in the forum with respect even when you disagree. If someone frustrates you, walk away from the conversation or ask for a moderator to get involved. Speaking of Moderators, they prefer not to be treated as "The Thought Police" but if any behavior infringes on the enjoyment of another user or is otherwise considered to be unacceptable in the moderator's judgment, it will be addressed in keeping with our view of ensuring that this forum remains a healthy environment for all simmers.

3) BE LAWFUL: Any behavior that infringes upon the law, such as discussion or solicitation of piracy, threats, intimidation or abuse will be handled unsympathetically by the moderators. Threats and intimidation may, at the moderator's discretion, be provided to law enforcement for handling.

4) BE FACTUAL: When you post, always be factual. Moderators will remove posts that are determined not to be factually accurate.

5) RESPECT COPYRIGHTS: Posting of copyrighted material such as flight manuals owned by Boeing or various airlines is not allowed in this forum. If you have questions related to copyrighted material, please contact a forum moderator for clarification.

6) RESPECT PMDG: We love to hear what you like about our products. We also like to hear what you think can be improved, or what isn't working. Please do tell us and we will always treat your feedback with value. Just be sure to treat the team respectfully, as they do put a significant amount of effort into building and maintaining these great simulation products for you.

7) RESPECT PMDG DEVELOPERS: All of the developers will spend some time here. Given the ratio of developers-to-users, it simply isn't possible for us to answer every post and private message individually. Please know that we do try to read everything, but developer workload is simply too high to manage personal contact with tens-of-thousands of users simultaneously. In most cases, members of the development team will stick to conversations in the forum and will not answer private messages.

8) RESPECT OTHER DEVELOPERS: PMDG has always advocated for a strong development community and we have many friends within this community. Every developer offers something unique that helps to make the simming community larger and more vibrant. We insist that you treat our friends respectfully.

9) RESPECT MODERATORS: Moderators have a tough job, and none of them enjoy having to stomp out negativity. If a moderator has to weigh in to keep a thread peaceful, please respect that effort and refrain from giving the moderator any grief.

10) If you require official support for any of our products please open a support ticket through the support portal,

11) This forum is designed primarily as a vehicle for the PMDG development team to interact with our customers, and for customers to interact with one another in a manner that is positive, supportive and assists in the general advancement of understanding the simulation and helping to make this and future simulations better. Any other use of this forum is not permitted, including but not limited to discussion of pricing policies, business practices, forum moderating policies, advertising of non-PMDG products, promotion of events, services or products that are not approved in advance by PMDG or any other topic deemed unacceptable by any forum administrator

12) HAVE FUN: This is the whole point of it all.

    + 1 Same problem, only with B737-800 and B737-BBJ2
    Alessandro Muntoni


      To be honest I think it’s an issue with MFS after long flights (in my case I noticed that with about 2 hours flights, on arrival). As soon as I restart the flight at the SAME gate and SAME airport my fps go back to normal. And I also noticed it always happen as soon as I switch views on arrival, not till I stay in cockpit. I found that spamming the windows key makes my fps return to normal too.

      One time I also had the sound stuttering before the FPS dropping.

      I found this +3k messages topic on MFS forums, talking about this issue…

      I hope it will get fixed in upcoming SU10.

      Exactly the same for me, after playing a few hours, FPS drops from 40 to 5FPS or even lower. Playing on high. Ryzen 7 3800x 32GB RAM RTX 2080 Super 8GB VRAM 1 TB Nvme gen 3 600 Mbs wired ethernet connection No AI …

        This might be specific to you, but doesnt seem to reflect hte problems others in this forum is having - at least not me.


      I submitted a ticket - they said they are working on a fix for it and to test out to aircraft come next update.

        If they manage to fix it, then I respect PMDG hugely because I honestly thought they wouldn't try and fix it due to it only being a problem for only a few customers.

        Thats great. Lets hope they sort it out!

      Hi there! I have a similar issue.
      After landing (even on shorter 1 - 1 1/2 hrs flights), I have fps that go down to 8-10 fps, whenever I switch to the outside view (or drone camera). In the cockpit, i still have 32-40 fps then. After 2-3 minutes, and switching between views, it goes back to normal fps. That only happens with the PMDG 737 (800, haven´t had it with the 700 or 600 yet).


        So, I did the same flight with the 600 and 700, and the stutters upon arrival didn't appear.



          Hi, I have the same issue and its been giving me a headache glad to know PMDG are aware of this. It happens when you are on outside( drone or free cam) view inside the VC its fine when you pan away from the aircraft the fps instantly comes back and drops again when you pan back to it very strange.


            I just tested the MSFS V1.26.5 PMDG-600 and -700 at KLAS (FlyTampa) no Live Wx.
            I did many screenshots but will only post the VC and outside for now.

            PMDG-600 (JANET)
            35.3 FPS VC
            40.8 FPS drone
            41.1 FPS outside
            38.8 VC bulkhead

            PMDG-700 (DELTA)
            31.9 FPS VC
            37.9 FPS drone
            38.3 FPS outside
            39.3 VC bulkhead​

              For the record I don’t have this stuttering issue after a 3 hours flight with the Fenix.

              I get these huge drop frames only with the 800 after like a 2 hours flight.

                i have seen this also but not sure how to repro it. it's happening to me right now... locked at 1/2 vsync. inside i get 30fps, outside i get 18fps. what is odd that with this exact same livery and setup (737-800, delta airlines) i was getting 30 on both in and out on my last flight. i don't know why it's different but i've definitely seen it a few times. the only difference the flightplan.. weather clear.. very strange..

                  Are the people experiencing these problems using texture mods and liveries? From looking at the most popular liveries on I can see that some artists have no clue how to compress DDS textures properly. For example, in the most popular Ryanair livery pack on there are some textures that are over three times the size as the PMDG ones, and I’m not taking about resolution but actual space on disk. All of that gets loaded into your VRAM. For example, there is one texture in that pack that is almost 400 mb while the PMDG version is only 89 mb.

                    For me it happens regardless of which livery I'm flying. Some liveries from ie are - as you point to - badly compiled indeed, but the problem still persists with the default one's as well.

                      Curious to know if SU10 has helped anyone with this issue or affected it in any way. It hasn't for me personally.

                        Haven’t tried yet but I was hoping to read some good feedback here…

                        maybe DX12 with upcoming Nvidia drivers may make a difference though…
