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, https://support.precisionmanuals.com

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.

    I accidentally came across a *temporary* fix for this issue.

    If you are in spot view and notice the stutter frame rate fluctuations, go to View > New View > Virtual Cockpit to bring up a secondary 'picture in picture' window of the VC. Then close it and the FPS fluctuations/stutter in spot view stops completely. This is UNTIL you change views and come back to spot view to which the issue re-appears.

    I recorded a video showing the FPS counter which may be useful for further investigation

    Very weird that this only happens on the NGXu for me. Any other aircraft works fine.
    Oh that‘s interesting, tried it out and yes the stutters stop with this method.

      No sense in tagging Kyle anymore, I don't think he'll be responding. He hasn't been with PMDG since early December.

        EDIT: Also note I have an external FPS Limiter set to 30FPS
        I am currently in contact with support regarding this issue. It would be great if anybody who has the same problem (besides DModjo and me) could write it here and also write which CPU is used.

            Just add a signature friend so that you won't forget to sign it in the future.
            Never the less thanks for sharing knowledge about FPS problem and how to fix it with the community.
            Hopefully PMDG can identify the problem and solve it in near future.
            All the best,

              I'm experiencing micro-stutters, they are occurring on a constant and cycling rate of every second, and they are very very short in duration, less than a 0.01 second. It only happens on the 737 NGXu; all other aircraft visual experience is very smooth. I already disabled the full screen optimization, with no positive results

              These are my current settings:

              P3D 4.5:
              - Vsync: off
              - Target frame rate: unlimited

              Nvidia settings:
              - Vertical sync: off
              - Virtual reality pre-rendered frames:1

              Nvidia Profile Inspector:
              - Frame rate limiter: 30 fps
              - Triple buffering: off
              - Vertical sync: 1/2 refresh rate
              - Vertical sync tear control: adaptive

              Monitor:
              - Refresh rate: 60 Hz

              GPU driver and NGXu, all updated to the latest version.

              Thank you all for you suggestions.

                Ensure that your minimum processor state of the energy profile of W10 is set to 100%.
                It seems to be critical with the NGXu.

                  First time I hear we can modify the CPU energy profile. Can you please provide details? I have the Intel Extreme Tuning Utility for overclocking, but I can't see any setting related to minimum power..

                    I mean the energy profile inside the Windows power options.

                      Already 100% in minimum and maximum. But thank you for the suggestion.

                        Sorry then, I thought it was worth checking out.
                        I got mad when happened to me, stuttering only on external view, no matter what I tried with GPU settings, P3D or Nvidia settings. As soon as I set the energy profile to high performance and checked processor minimum CPU state the stutters were gone here.

                          Update:

                          Just set all the settings to the lowest possible, and the micro-stuttering still occurs. It only stops while the simulator is paused, and the movement from the external view and the virtual cockpit is really smooth, no stuttering at all. As soon as I press pause again to continue, the stuttering resumes. Definitely is something in the latest version, because that stuttering wasn't there until I updated the 737 NGXu last weekend.
