okay bitches
so you just installed the new firestorm version and now suddenly the anti aliasing looks like ass and everything seems a bit more drab and depressing (and also all the normal maps look more detailed)

i cant do shit about the anti aliasing

to bright back the brightness you have come to expect of SL, go into your preferences, then the graphics tab, then within that the rendering tab
you'll see at the bottom there's options for "Tone Mappers", you're gonna want to set it from ACES to Khronos Neutral, if you're curious why just check the picture i put on here
i think the only objectively correct way to set it would be setting it up for substance painter, in which case you'd use ACES, but also who cares because it looks sad like a 2010s shooter
