It looks like consoles (maybe pc as well) sufferin memory leaking since 10 dec. patch or near time. Blurry textures in unjustified empty ramlight areas like tunnels, crashes that never occurred before (tunnels) , Out of Memory issues randomly on many previously well performative routes. Litteraly the longer you play the worse it gests (first textures, than stutters, than sound and finnaly freeze and crash). Few months ago (su 13) Msfs2020 suffered similar problems and only enabling huge memory cache file (like 64gb) prolonging time till game inevitably freezed and crashed. DTG whatever you change in core of this game in last 10 days or neraby, revert it or reevaluate it please.
