I thought I'd have a go with the beta and enable the experimental multi-monitor support, and give DLSS a try.
DLSS - in single monitor mode it certainly adds some extra fps (I'm using 1440p with a 3080FE and 3700X) but as others mention above, even in Quality it definitely adds some blurriness when things are in motion. It also makes a blurry mess of many of the cockpit dials and info, so somethings not quite right there.
Multi-monitor - blimey this adds massively to the immersion. My set up isnt ideal as I have my main 27" monitor to the left, two 21" old 1600x1200 LCDs to the right of this (mainly for retro use) and then one 24" 1920x1200 above the main monitor. Even with this less than ideal set up it's still a very nice experience. Performance tanks obviously, and I'm routinely down at 20fps when taxiing out or overflying built up areas like London or New York, but once higher and over the country I'm at 30-35fps.
Performance seems to be Main Thread limited according to the dev mode info, so it's actually possible to disable DLSS in these circumstances and improve visuals without a drop in fps.
Adding extra monitors left and right is relatively simple but there's no perspective correction. You can move the camera up and down, left and right, plus some roll, but you can't change perspective. So when flying around when you change your aspect the left and right views arent seamlessly matched to the extremities of the main display. Hopefully they've improve this.
DirectX 12 is still garbage. According to MSFS2020 forums it seems some nvidia memory management has been dropped, so maybe that's why my 3080 is a 12-15fps stutter-fest with DX12.
