Got em on Series X.
It’s hard for me to fully gauge as I haven’t flown much in recent months, very rare at nights. I reckon so far they offer a mild improvement at best. I don’t know if it’s an Xbox LOD issue but have noticed strange screen space pop ins with surrounding buildings alongside their lights going off and back on again. I think the angles of the lights themselves are weird, specially the runway guiding ones seem to flicker out and back into existence on approach. Something has been out of wack for quite some time with night lighting, I suspect LOD isn’t quite there which might be part of the problem. It has been better in the past.
