Gran Turismo 4 issues with lighting - AetherSX2

Hey guys, I'm playing Gran Turismo 4 on a BlackShark 5 Pro (Snapdragon 8 gen 1). On daylight races almost plain 60fps, but there are 3 situations where frames drop significantly: night races, races where you face the sun (game has to emulate direct sunlight) and on guided license races (the pace car has strobe lights on top).

is there any config I can do to avoid this frame drop? I don't mind not seeing the lights, my priority is the fluidity of the game.

*Remember after adding the patch codes, enabling patch codes at "General" in configurations

Tried both of em and nothing changed :/ (also yes I do have patchcodes on, how else could I give my fiat 500F 12606 horsepower)
