Thanks for your testing and sharing your results guys and girls! 
An easy way to find your flightsimulator.exe is to go into Process Lasso, while FS is running, Right click on it, and select “Locate on hard disk.”

I’ve tested this sitting at Heathrow gate 555 (premium version with the handcrafted airport) and it made absolutely no difference whatsoever.

This is what I experienced as well. I didn’t see any increase in FPS, but it’s definitely smoother now.

This don´t work if the game is from the Xbox for PC app. It is impossible to get access to the flightsimulator.exe. Is there any way to access to the .exe file?.
Just to follow up on this from yesterday after flying a bit more. As I wrote before this definitely made a difference for me–not in FPS, but how smooth the game runs.
I decided to push things a bit–and increased my res from 1080 to 1440 and kept rendering at 100–I lowered my terrain and object detail and managed to crank out 21-25FPS at the higher resolution, which I was never able to do before.
More importantly that 25 FPS “felt” different. If I put myself into a 360 turn there was no stuttering or micro stops at all–it’s really playable at this settings. I did a few touch and goes and no problems at all.
I’m not sure what this change is doing, but there is definitely something working in my advantage on my machine.
Ahh, good old fashioned placebo effect “performance improvements”. Good to see that msfs forums are keeping up with the times.

Nope–the game is definitely smoother–I’ve got close to 100 hours since the release and have benchmarked my machine with the settings to try and eek out a bit more performance–I have to I’m running an older 4MB GPU 
No placebo for me–I’m going to keep my increased settings after making this change and the game looks and flies better…nice improvement for me.

See see, nice to see it actually does improve for some of you at least.
I gave it a second try yesterday and for me I must say it did literally nothing.
But that’s fine. The sim runs fine for me anyways.
There’s also a second setting this guy from the video mentioned, wich is the DPI setting way down in the the same tab.
He said if one is setting it to “Anwendung” (wich is application in english I suppose) it will give even better performance.
But I never tried that. Don’t know what this is doing, so I skipped that.
Maybe someone more techy knows if that even makes sense.

this worked for me
Would you mind summing up in text what the video is saying?
its nothing more than a but of german lets play and my tutorial i wrote a bit above
Another 580 nitro user! Thought I was the only one lol. How is the fps for you in jets?
I’m locked to 30 but cockpit labelling the GA’s are still blurry at 1080, unlocked I get about 40.
I’ll try this tweet later see what happens.
Guys, this hack still works but after a complete reinstall i need to know how can I acess the Windows Apps folder!! The Original video is no longer available and the video from this indian guy is not helpfull.
I know it is dead simple,but I have forget how to do it.
So,please,need HELP!
Then this is a bug or poor design on Asobo’s part. There are fullscreen modes in DirectX that can bypass fullscreen optimizations.
and… in case of dpi scaling is at 100% , it shouldnt matter in each case 
@Semor76 if still intressed may be Take ownership of the Windows Apps folders
Thanks but It did not work on my end. ■■■■,I need that video…LoL
In VR disabling fullscreen optimizations (FSO) causes the mouse to stop working after awhile. I suggest you do not turn off FSO if you fly in VR. Since finding this bug and therefore re-enabling FSO, I haven’t seen any performance degradation so I don’t think it’s necessary any longer anyway.
Here’s the bug. It started after the SU8 update. The mouse in VR and the mouse pointer on your 2D screen are not perfectly in sync. What happens is that after a time of moving the VR mouse around, the 2D mouse pointer ends up at the top of the 2D screen. So while in VR your mouse pointer is normally positioned, on the 2D screen it’s at the top. When this happens the VR mouse stops working. You can’t click on anything in VR when the 2D mouse pointer is at the top of the 2D screen. This doesn’t happen if you don’t disable FSO.
Is that bug also pressent in Windows 11 or ist it a 10 only Bug?
