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.

    Here is a comparison with default weather and same position with the NGXu and B747-8:

    2019-11-16_10-5-41-8.jpg
    2019-11-16_10-3-27-125.jpg

    The B748 is butter smooth with mid to high 40's. The NGXu frames are unstable and vary between 20 - 35 frames. I've been testing a lot since the last update and can't seem to find a happy balance. Any external views are fine, though.

      Out of curiosity, what happens when you try that same scenario with an FPS limit on the NGXu displays that matches the 747's?

        I always set my FPS limiter to Unlimited simply because the frames tank on my system. This goes for any aircraft. Having it at unlimited keeps it smooth. I don't tweak any of the CFG files either.

        EDIT - Sorry I may have misread your question. Are you talking about the FPS of the displays or the sim limiter?

          Sorry, I wasn't clear - I meant the refresh rate on the PFD/ND of the NGXu. One variable that's different vs. the 747 is that the displays are set to unlimited by default, whereas I believe the 747 has a limit of 25 or something close to that.

            That's something I never tried yet. I will have to take a look. I appreciate the suggestion!

            After looking at the display settings in the B748, they show the same default values as the NGXu:

            By the looks of it, the B748 has it set to unlimited as well? Or am I missing something?

              Ah, for some reason I thought it had a default limit on FPS. It still might be worth comparing with a limit on the Xu's displays. They're way smoother than what's in the 747, but maybe that comes at a cost in performance.

                My performance about the same before and after the update with initial tests at FSDT KORD FPS locked at 30 FO display Off I get 22 to 28 FPS day/nighttime HUD in use /lights On /Off/at the gate or runway tests / smooth panning / no problems to report.

                    Same here. I can add that performance after last update is even worse. [8700K @ 5.2Ghz, 2080TI].

                      On my system the NGXu has a really bad performance especially at night with all the DL. Compared to the 747 and 777 it is definitly worse for me. I use heavy scenery like EDDF and never had a problem with PMDG products before.

                        Running a 1080ti/4.2 CPU and am seeing the same decrease in performance, Maybe 30% degradation over the original release.

                            Same over here, FPS on original release was 'so so', got worse after the update.
                            Running standard settings in P3D on a i7-7700/4.2GHz plus a GTX 1080.
                            It's a pity, because PMDG released a really beautifull new 737. Grounded over here until further notice.

                              Same as everyone else. After the last update what should increase performance did the direct opposite.
                              A significant decrease in performance is noticeable very disappointing.
                              The release NGXu was better on performance and even that performance was bad compared to all the other PMDG releases.

                                On my rig it is only AT NIGHT ... during the day, the FPS are smooth and not fluctuating up and down and sideways. But at NIGHT, even standing still at the gate, the FPS are a dismal 14+ which is only aggravated if the airport has its own DL.

                                I've started a thread on this specific topic with attached screenshots because it seems PMDG does not believe us ...

                                  Absolutely the same poor performance issues to report from my side. I remember after purchasing the NGXu on the 1st day it was released that the performance at night seemed OK. Now, whether it is due to updates or not, performance is very poor at night from the VC. The key issue is that the performance is much much worse than the original NGX and all other PMDG aircraft (which I own). One of the the best features of the original NGX was that I could always get 30 FPS locked no matter what time of day and no matter which airport. Better than most other high-end aircraft. Now flying the NGXu version for me is not really that enjoyable anymore (at least at night). Not smooth.

                                  I am still looking through the forum for posts concerning the poor performance of the NGXu. It seems to me that PMDG have not responded to any of the posts on performance but I may be wrong. I am sure they must be aware of it - but it is not evident from any of the responses / forum threads.

                                  Does anyone know if this issue has been acknowledged by PMDG and if they have any recommendations / advice / solutions for users.

                                  Cheers,
