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.

    DC-6 has become unusable after WU6 (MFS2020)


    After WU6 I've faced with DC-6 issue: in every flight appr. in 250-300 miles after start FPS drops from 35 (in the beginning of flight) to 10, textures of terrain and clouds degrade to "low" level and after several minutes MFS2020 totally freeze.
    I've checked MFS2020 just after these issues by repeating that flight with "default" A320 - no were any issues during all flight: textures were "ultra", fps 35 as normally, etc.
    So, I guess the problem in DC-6.
    Has anybody faced with the same problem?
    Any ideas how could I solve this problem?

    Have you tried a fresh reinstall of the Dc6? I didn't have any World update issues, but I have had a few issues just prior to the update such as certain (not all) clickspots not being usable, so last night I did a complete reinstall of the DC6 and everything is fine now.

      Yea, had this problem with the A320fbw during a long haul flight. Turned out to be my Nvidia 2080ti overheating as the simulator had been running a long time. Basically the GPU switched off but the sim was still running. Went from 35 fps to 8. I saved the flight let everything cool down for 30 mins and retuned to my normal FPS rate. If you overclock CPU and GPU it may be part of your issue. Not had it with the DC6 though, but I am due a long haul with it this weekend..KFFL to KSAN.

        Just FYI I've flown multiple flights with the DC6 in all sorts of weather and in the new locations (Germany, Austria) and have not experienced the FPS issue, so I hope by reinstalling it fixes your issue.

          I experienced the same problem today, and I checked that it was not due to the CPU or GPU temp. When I paused the game with esc, the fps got back to 60fps and the GPU usage returned from 10% to normal 60%. But when resuming to game, the GPU refused to run in full power, again. (i9900k with 3090).

              It seems that in some instances this behavior can be reversed with turning off and back on ai and multiplayer traffic.
