Flight Simulator FPS Drops / Stuttering...Video evidence provided.

I have the exact same issue. The weird thing is, when I press the "Windows" button to pull up a view outside the game, it runs fine in the background, so it's not a performance things. Try it, you'll see what I mean.

I know it's not my PC and it was working fine before this patch:

Intel i7

32 GB RAM

Nvidia GeForce GTX 1080

All drivers and OS up to date.

This is so frustrating.

I think it's true the lower system requirements to run this game are incorrect unless a person is good using all low settings. I think it's far more accurate to consider the "recommended" system pc requirements as the minimum requirements. Having said
that the game is a great start for the sim especially once stutters and crashes are overcome with fixes.

For me, I've quite a humble setup with Core i5 6600k, geforce 960 and 16 gb DDR4; facing the same issues as much more powerful setups are facing. I was seriously thinking of upgrading my rig but I'll hold that off for now until some patchwork is done by
Microsoft.

As for the sim itself, I'm awestruck by the clouds, lighting and scenery. I think it takes care of many ambitious projects in other sims, especially related to satellite imagery. As of now, the sim is in it's showcase mode and it would not be right to expect
a perfect thing right from day one.

I have been playing some more as well...I've also been keeping my eyes on the benchmark test (MSI Afterburner Overlay). Both my CPU and GPU average around 70-75 degrees celsius (don't think those temps are anything to worry about on a graphically intensive
game) and the FPS averages around 70ish when the game isn't stuttering...and this is on the High-End settings on my RTX 2070 8GB, i7 9700KF, and 16GB RAM.

Game often seems to stutter on the prologue before a training mission (you know that screen where it shows you your plane and prompts you to press to start the mission...that screen). At the very start of a training mission it will stutter for a bit then
it will promptly go back to normal. I am pleased to say I've enjoyed a few training flights mostly stutter free except for one or 2 mid-flight incidents like the one in the video I put in my original post...the rest have mostly been on the prologue screen/very
start of each mission.

Whenever it does stutter I notice the CPU suddenly goes up to 100% usage...when the stutter ends it goes back down. So whatever is causing the stutter sounds to me like some sort of rogue process/memory leak maybe? Idk...whatever is causing it is a sudden
spike in CPU usage anyway.

I hope they fix it with an update.

Yes, I installed that driver last night.
