Sure sounds like it. 

So, somehow MSFS doesn't seem to be hooked.
Changes to e.g. Limiting the FPS does nothing.
The control panel ("CRTL + Shift + Backspace") does not open either.

I'll disagree with you, here is a very good article from DirectX Developer Blog: https://devblogs.microsoft.com/directx/demystifying-full-screen-optimizations/

Under Windows 10 FSE and Borderless Window are non-issues from a performance perspective. From that article:

With the release of Windows 10, we added Fullscreen Optimizations – which takes full screen exclusive games and runs them instead in a highly optimized borderless windowed format that takes up the entire screen. You get the visual experience and performance of running your game in FSE, but with the benefits of running in a windowed mode. These benefits include faster PC commands such as alt-tab, multiple monitor set ups and overlays. We have extensive performance data that indicates that almost all users who use Fullscreen Optimizations have equal performance to Full Screen Exclusive. 

...

To get back this performance overhead, we enhanced the DWM to recognize when a game is running in a borderless full screen window with no other applications on the screen. In this circumstance, the DWM gives control of the display and almost all the CPU/GPU power to the game. Which in turn allows equivalent performance to running a game in FSE. Fullscreen Optimizations is essentially FSE with the flexibility to go back to DWM composition in a simple manner. 

If you are have lower FPS or latency issues, then it's likely you have something else running in the background that is causing that problem and needs to be addressed (reference the article link above).

Cheers, Rob.

Well let's agree to disagree then 🙂 , because I have witnessed the physical proof on my system that this does work. I have a highly expensive and optimised system, I know what I am doing (almost!). I have nothing in the background causing any such things. 

 

No, this isn't for steam games only, it is also for non steam games. I use the windows store edition. However, you DO have to have steam installed and running (strange, yes). 

 

PS I quote that exact same blog article on page two of this thread 🙂

I have this running without Steam.  I have a Gamepass Standard version of MSFS.  Up until yesterday it was failing with a SpecialK64.dll error but once I had installed MS Visual C++ 2015-2019 Redistributable x86 and x64 it has worked fine ever since.  I've to do some testing as to whether it is of any benefit but at least it is running.

Do you have the flight simulator profile settings? You must make those changes too.

Never managed to even run it. Trying to open it nothing happens.

I do have the profile settings. I followed the procedure as in the earlier Special K posting

So would it work better none a G-Sync do you think, I find RTSS is really good. But if its better?

I have compared RTSS at x/2 versus vsync to a 30Hz capable screen, and the latter delivers equally smooth performance at much lower cost to the main thread.  With RTSS the main thread in either MSFS or P3D is always close to maxed, whereas w/ vsync to 30Hz goes down by up to 60% w/ no loss of 'performance'.

Actually i have got the Steam version and can't get i to work too. 😞

Yes but I don't use vsync as my screen 120hz, so i have no idea if this for me would be better, thanks for the info all the same.

I just slopped into my 30Hz capable screen I certainly was not looking for it when I made the purchase several years ago, but feel very fortunate it does once I learned about this option.  Dell UltraSharp U3415 3440x1440 curved.  It is not g-sync nor HDR capable, but it does offer what they call Dynamic Contrast.

Using the RTSS method the main thread processer will crank out 100% of the pre-renderings it possibly can, even though they will be clipped by RTSS down to 30.  I find it odd people here will clamor over RTX 3090 or getting few more gHz out of their CPU, when this maneuver really relaxes both sims--P3D & MSFS.  Vsync to 30 does more than just offer smooth flight, free from stutters, provided of course settings don't exceed CPU/GPU raw capabilities.

nVidia users might want to play with low latency mode in the nV control panel,  and possible check to see if Windows 10 "Hardware Accelerated GPU Scheduling" is enabled.

Reduced GPU utliization about 12-15% for me, setting LLM to Ultra from Off.

That doesn't make sense to me, I have MS Store version and I shutdown Steam before running any flight sim and see no difference in frequency of long frames (stutters).  Do you have the nVidia GForce Experience overlays disabled?  If you are seeing a difference in FSE and Windowed under Win10, then something else is the source (running in the background).

Cheers, Rob.

RGB software for example is very often a major resource hog.

Did it affect image quality / frame rates in a good way, or a bad way?   Sorry,  I'm a bit dense at times.
