When I first applied this update it seemed to really help with the stutters. Now 10 hours later I'm right back to where I was before the patch. I'm not convinced now this patch did anything. Guess time will tell. 

it was not meant to fix much anyway, only the stutter with simconnect.

but then, i never had it stutter much, except for the very occasional loading.

i think the stuttering some have is mainly due to something at their side.

Placebo.

Stutters almost gone in my rather old rig.

Simconnect finally working for the bridge between Aerowinx PSX and MFS - now we have the BEST EVER combination of a 747-400 simulation, specially for those with multiple PCs and displays ( still applicable only to the PSX panels ) ! WOW !

I'm getting 3 time the stutters after update and every few minute CPU spikes to 100% with freezes.  I had very few before the update.

The CPU spikes are fixed with the Process Lasso tweak. 

Yes, all very strange.  It will take some time to settle down, just like other sims.  I get better frames, really fluid, but I have also had some of the long pauses with CPU at 100% (normally it is the GPU at 100% when it is running well).

Luckily, I am not getting the annoying micro-stutters though - they can be unbearable.  AI traffic brought that in for me, but I turned it down to 10% and all was good again.

I am wondering if rather than changes to the code, the update might have reset a few settings.

I was using a different process before the patch to do something similar, but this worked 100%.  No stutters, Thanks!

I'm with you there. My initial free flight test suggested stutters were all but eliminated, but a couple of hours of the bush flight challenge and I can see that they're still there, though possibly briefer.

I have an i7 6700K, so only a quad core. I decided to track CPU and GPU via task manager to see what's happening during the stutters. Interestingly it was very apparent and consistent. I get a half FPS stutter that appears to be caused by a 10% DECREASE in CPU usage and an associated dip in GPU (most likely the CPU dip is causative of the GPU dip). RAM usage is solidly consistent throughout.

Track your disk usage and network usage as well.  I've seen fairly consistent spikes in both of these during stutters as MSFS loads new streaming scenery.

People with really fast Internet and using SSD will probably see fewer or shorter stutters than I do in such conditions.

Is it the same Process Lasso Tweak that been around for a few years??

Choose any game and select "Classified as Performance Process"??

Not the best test scenario because the bush flight challenge saves your position every minute, so you are having constant disk write cycles.which are sure to cause a brief hiccup unless you have an SSD.

It doesn't fix my issue where moving the mouse cursor causes some window focus issue and FPS goes choppy. It seemed to work a bit better at it before the recent patch. But it has helped a bunch of people so might be worth trying still until they release the next patch.

Internet usage didn't show anything consistent with the stutters (it was quite noisy throughout). I have 200Mb dl and 20Mb ul speeds and generally with low latency, so I'm not expecting anything there.

I have the sim installed on an M.2 NVMe drive and my OS and Windows Store, et al. on a seperate M.2 NVMe drive. I wasn't expecting those to be a problem but of course they could be for a host of different reasons. There are multiple scenarios one can envisage but one is that there is something in the sim code that gets caught up and so the CPU has a temporary "brain fade" with respect to supplying the GPU with information. It's interesting that it's quite consistently a 10% drop in CPU usage and and exact halving of FPS. The GPU drop is more variable.
