I've decided to take some time to showcase the issue that is plaguing every single game in existence right now and for us our flight simulators. The reason is because some games run on full screen windowed mode. Something is broken that isn't allowing the Antialiasing to be implemented on this mode. Full screen windowed mode works differently than exclusive mode. I know that Prepar3D runs on FullScreen Windowed Mode and not Exclusive Mode.
In the shots I used an older title, Microsoft Flight Simulator 2004: A Century of Flight, that I knew used to work properly with Antialiasing on Windows 10, but is no longer working correctly. I'm a flight simmer mainly, so the anti-aliasing is of utmost importance especially for distance viewing. Without it, it takes away from the immersion.
Exclusive FullScreen mode applies the Antialiasing, but it isn't as strong as it should be, it still has issues with the latest drivers and it comes with shimmering in the distance as other people have noted. FS2004 does not use the fake windowed full screen mode, but rather EXCLUSIVE full screen mode, so it helped to find the problem.
Notice that I've checked the box for Anti-Aliasing in-sim which on this title at its prime time caused the game to look incredible, and many users cautioned against using that option as it was taxxiing on the system resources, but now even that check-box option looks terrible. The AA implementation that is used for this sim is MSAA and I believe it's supposed to be x8 when selecting the box.
This isn't on my main desktop but rather on my Area 51m Laptop. 9700K/RTX2070 using the latest windows build 20H2 and latest NVIDIA Driver.
Please observe the images, I've even highlighted the differences. I took the time to do this so that someone either over at Microsoft or NVIDIA can fix it because this is happening on ALL games/titles.
I've read on some forums that they couldn't find the solution and have been living with this issue for a while now and that's because their games run in windowed mode, I'm helping to narrow the issue down.
On another forum someone stated the issue could be "dirty" electricity, but that's nonsense because I took my gaming laptop to my parents house to do this where things used to work, so therefore it has nothing to do with electricity. It's something within the OS or NVIDIA driver that's not allowing this to work properly.
I hope that this is helpful to narrow down the issue, engineers can now work on fixing windowed mode anti-aliasing, although the AA looks a little better on fullscreen, it isn't up to par with how it used to be before all this madness occured, which causes shimmering textures or flickering.

Let me know what you guys thing. Thanks for taking the time to read my post.
