A few of us reached out to PMDG regarding the ongoing issue with pulsing stutters in the 777, and I wanted to share a temporary workaround discovered by another user that seems to resolve the problem.

The stutter isn’t the worst I’ve seen, but it becomes quite noticeable, especially if you're watching for it. After some testing, it appears the EFBs are the culprit. Specifically, certain EFB pages cause a recurring pulsing stutter every few seconds. You can reproduce this by enabling the FPS graph in MSFS 2020 or 2024, where you’ll clearly see red frame time spikes that correspond to the stutters (as shown in the video below).

Interestingly, changing one EFB to the Weight & Balance page removes the stutter from a double pulse to a single one. Switching both EFBs to the W&B page eliminates the stutter entirely. While many have noted this issue most during the flare, it’s actually present throughout all phases of flight.

Hopefully, this helps others experiencing the same issue, and with any luck, PMDG will be able to implement a permanent fix in a future update. Here is the thread regarding this issue: https://forum.pmdg.com/forum/microsoft-flight-simulator-2020-2024-products-discussion/pmdg-777/general-discussion-aa/355337-777-200er-in-msfs-2020-periodic-stutter

 

This is likely why they didn't release the 77W on Friday reading that thread. Hopefully they solve it soon. 

sorry for digging up this old post, but with the pmdg 738 I have still the same problem. only when I put both EFB's on Weight and balance page the 5 sec stutter is gone... Has there ever been a solution for this?

Having difficulty understanding, and with the video having no sound, I'd like to rephrase.

To eliminate the stutters specifics to the 777 (and perhaps the 737), is it necessary to display the "W&B page" on both EFB for the entire duration of the flight?

Thank you in advance.

yes, that's the only way I can stop this 5 sec stutter. Don't understand...there are many reports but still no fix...I think.

on the pmdg forum  a user posted this;

Just found a temporary workaround for this issue (with a downside). It seems to be related to the current time on the statusbar of the EFB, the stutter happens when the value of the HTML component is updated, if you comment this line, the EFB will only show the time as 00:00 but you won't have stutters anymore on the main page.

In the 777F version you have to comment the line 69087 of the PMDGTablet.js:

Before: time_el.innerHTML= StatusBar.time_local + " / " + StatusBar.time_utc + "";
After: //time_el.innerHTML= StatusBar.time_local + " / " + StatusBar.time_utc + ""

Not a fix, but if you don't use the current time on the EFB it might be useful.

EDIT: You can also minimize the stutter so it happens only when the time changes instead of every 5 seconds.

Find the following code: time_el.innerHTML = StatusBar.time_local + " / " + StatusBar.time_utc + "";
And replace it with these 2 lines:

const newText = StatusBar.time_local + " / " + StatusBar.time_utc;
if (time_el && time_el.textContent !== newText) { time_el.textContent = newText; }

 

however this is a workaround which I don't want, because changing times in EFB will interfere with the flight plans etc.
