Flight Path Marker weird behaviour during Turbulence or Storm

As you can see from the video

Some info about what is happening here: the Viggen measures wind direction and strength using three Doppler-antennas under the aircraft. Since the antennas is pointed downwards relative to the aircraft the Doppler only works when wings level relative to the ground. The measured wind (measured aircraft velocity over the ground minus the calculated aircraft velocity) is the added to the flight path vector so the pilot can put the fpv somewhere and that would really be the direction the aircraft is flying. In DCS turbulence is simulated through 2-second wind gusts that can be seen on the FPV. There is a filter to filter out small changes, IIRC it should take something like 20 seconds to "tune-in". Appears the filter isnt working. In the video you can see that when rolling the fpv switches between using the live input from Doppler and the last input from it.

maybe you should set up the same weather for the A-10 and F-15 and compare...

I flew with bad weather with all aircraft this is the first time i see fpv behave like this

Then again Viggen is probably the earliest aircraft in DCS that has one.

Yep definitively in the video the FPV movement looks too brisk and the oscillation is excessive, it doesn't seem to match with the real a/c movement.
