I just read your article.  Very interesting!  Thanks for putting the time in to try to solve this.

By the way, do you know what is meant by 'manipulators'?

Thank you for your kind words!

As for your questions, some would say these are people making other people purchasing a game pretending it is a simulator 

Kidding apart, to me this is the task in the game which is handling the interaction with these inputs and running most likely through (or with) CoherentGT. This would encompass the mouse click spots and the controllers. But I'm really just speculating here.

I've never suffered much of the stuttering. After the fix something new I hadn't before though  : isolated small pauses of 2/3 seconds, once or twice in an average session of 60/90 minutes  I could come my 4G ISP of course but it came after the fix. Anybody else ?

I have a very similar PC to yours. I overclock my 4770k to 4.3 GHz but have 32 GB RAM and a 1070 with 8GB VRAM, also running 1440p BUT with Gsync. MSFS is very smooth on my setup and I have 40 FPS on average. You need to overclock that CPU, add more RAM and see about upgrading your monitor if it is not Gsync. Then if things are not smooth you need to turn things down or off in MSFS. 

I also have Gigabit internet (average about 750 Mbps) and that is a new development for me, so no idea how much that is helping. Previously I was averaging about 30 Mbps at the old house.

Thanks. As I said earlier, I have noticed these pauses only recently, after the fix. And I understand from this thread that fellow simmers with more powerful hardware have the same problem.It is not stuttering just a small pause now and then. 

I had the 4770 overclocked in P3D but went back to the standard clock   whith MFS. It has already 8 years.  My flying experience is smooth (a credit to Asobo) so I let it like that.

I will not upgrade my sim around a 4770, I wait for the graphic cards to come back to the market to build something new.

I have 32 GB RAM and a RTX2070 with 8 GB, and since the last sim update I get horrible stutters. CPU usage mostly is <70%, GPU works at >95%. The RAM usage seems to have been limited a bit by this update, as MSFS now never uses more than 16 GB, while prior to the update peak RAM usage could be as high as 19 GB.

So you might hold back the investigation into better hardware and wait for Asobo to fix the problem.
