Viggen starting heading 180 degrees out?

[Mr_sukebe]

Anyone else experienced issues with the Viggen heading being reversed in the Nav system on Kola?

The compass is showing the correct heading, but the Nav system is the other way around.

Hello!

I just tried DCS and Kola with the AJS 37 Viggen a couple of minutes ago. (Single player)

I started in the air and so far so good.

When I landed at Vidsel everything was fine until I came to the second half of the runway.

After passing the middle of Vidsel runway, my compass and SI (HUD) indication turned almost 180 degrees!?

I landed with "skedesväljaren" in "LANDNING/PO" and had landingclearance for visual landing at rwy 11 from ATC. 

At final approach, heading on the compass was fine, also on touchdown but after a while the heading changed almost 180 degrees!?

 

Perhaps I have done something wrong? I do not know?

 

I have attached a couple of screenshots taken during landing.

My system specs:

Intel i5 Cofeelake 12400F, 64GB RAM, Nvidia Geforce GTX 4070 12GB, 2TB SSD, Thrustmaster Warthog HOTAS, Virpil combat pedals, AOC 27" HD gaming monitor.

And then there is this. Also a Heatblur aircraft, also on the Kola map.

Yep, it's not just you. It happened to me too, but only starting today (yesterday was still fine). But I found an easy fix: I just deleted all my fxo and metashaders2 data and presto! You should give it a try.

I'll give that a go later today.  My thanks for the suggestion.

Seems a bit of an odd "fix", but hey, we're talking about IT.
