AntiAliasing broken in-sim. Please fix

Hello guys, I notice that this has been discussed before. But I cannot for some reason get anti aliasing to work on any of my 3 gaming PC’s for any games much less flight sim. Is there something broken in Windows 10 or what? This is really beginning to aggravate me to be unable to solve this issue. FXAA works a little but it’s a blurry mess. I know MSAA and SSAA looks really jagged for what should be completely smooth AA…

NVIDIA isn’t helping on their forums and I keep sending feedback to Microsoft but no replies. I have done a lot of testing but I’m not able to pinpoint the issue to one particular thing. I’m wondering if this is something that Microsoft messed up in an update for Windows.

My PC’s are as follows:

Main Desktop - 10900K, GTX 1080Ti, 32GB DDR4, 2TB NVME, 144Hz 2K GSync.
Alienware Area 51m R2 - 10900K, RTX 2080S, 32GB DDR4, 2TB NVME, 360Hz GSync 1080p
Sons desktop - 8700K, GTX1060, 16GB DDR4, 500GB NVME, 60Hz 1080p

It doesn’t work on any of them… even after loading Windows 7 and 8 on these machines, nothing…

This hasn’t just affected MSFS but also XP11, P3D and DCS World.

Anyone know of a solution?

To recap no setting fixes AA for MSAA/MFAA/TXAA.
Seems as though it’s an update problem from Microsoft.

It’s the same issue as another user reported with the title: Anti-Aliasing completely broken at 1080p.

Can a dev chime in on this issue?

Thanks.
