Hello 
I cant see the stutter at 38:45 but its perfectly seen a horrible stutter at 38:47 exactly in the moment when the wheels touch the ground/runway.
I have the same problem. Not only nowadays but I have suffered this problem (yes SUFFERED) at least through the last 12-13 months. If I start the sim and make a flight with any aircraft (the cessna 172, the B747, the DA62, the FBW A320, or ANY plane), I have the stutter that its seen in the video no matter where I land, it can be in a massive airport like KATL, EGLL, KJFK or a tiny one lost in the middle of nowhere like SCIP… even I can land in the middle of the Sahara desert where there is NOTHING to load and have the stutter when the wheels touch the ground.
Its very curious but if I make a second flight when the same aircraft its very possible that I will not have the stutter when I land, then the probably of having the stutter decreases from 100% to 30% aprox. I think the problem is related to the sim cache but even if I turn on the sim cache option I still having the stutter the 100% of times in the first flight and the chance to solve it in the next flight is high.
So, what I always do is to start the sim and make a veeeeeeeeeeeeeeeeeeeery small flight with the desired aircraft, just to take-off and land immediately even in the same runway just to have the horrible stutter/lag when the wheels touch the ground, then to finish the flight and make the second one that is my desired flight and can be as long as I want and the chance of solving the stutter when landing is high but NOT 100% sure… sometimes even in the second flight I have the stutter… as I said, the chance of not having the problem during the second flight its around 70% but not 100%
I tried all kind of solutions like downgrading the graphics, flying without live weather, flying without live ai-traffic, flying without addons, and nothing helps. Even I have the impression that if i downgrade the graphics the problem is bigger. The only kind of partial “solution” is what I already described above.
Everything what I say its just my experience and I just want to share it with all of you so can help you a little bit.
Asobo should fix the problem. We shouldn’t be experimenting and finding solutions for horrible issues like this one that its not new… the stutter/lag problem when the wheels touch the ground has more than a year and NO real solutions from Asobo side
