I don't know if the updates reset the options (probably), but I'd bet that it is your issue; you'd have disable weather/lighting effects or whatever, the update re-enabled them, resulting in you having issue, or something like that
At the very least, the fact that we don't have the same issue than you means that it's not on their side, or technology is now into discrimination :Ambivalent:
Otherwise, that'd be really odd, as they actually even reduced the amount of performances needed when fog is displayed
"Fog uses less performance then before for all your potato PCs." (cf. https://pokemonrevolution.net/forum/viewtopic.php?p=243272#p243272)
Anyway, hope you'll figure this out ~
