investigating Consistent stutter as soon as taxi starts

[Nealius]

As soon as I start taxiing I get a consistent stutter, particularly noticeable in VR. Oddly, when this stutter occurs the navigation panel's WP/AD switch gets reset to AD after I had set it to WP during startup.

Track too large for direct upload, so adding to Google Drive: here

Using the Germany CW map.

I notice the same. you can see it in my video here: 

Attached is a short track

If you watch carefully, you can even see it in Wags "How to Start a MiG-29A Fighter" video around the 14:02 mark.

Unfortunately I've also been noticing this issue after a cold start when taxiing out to the runway. I also noticed the switch on the navigation panel gets reset from ''WP'' to ''A/D''.

You only see this if you start with external power. It doesn't happen with a Battery start

I have the same issue, don't know what caused it

I also experience this.

Yes, it is always present. But for a very short time.

I've got this problem since last update.

please include short track replays and dcs logs from the session so we can investigate it further.

Here's a vid highlighting the stutter/NAV computer glitch plus a TRK of the whole start-up. 

If the player has moved the NAV switch to WP, the stutter will reset it back to A/D. This happens whether or not a DTC has been loaded.

There is no stutter/NAV glitch when starting from battery power.

No need, it was reported with track and examples already some time ago:
