Rain graphics in FSR 2.0 and FXAA.

I am not sure if its just me but it feels like rain particles are very thin and not visible in FSR 2.0 compared to FXAA. The problem is any other setting cause weird lines on edges of farway linear struvture like building if i am not using FSR 2.0 and rain feels near invisble in FSR 2.0. Is there any soultion so i can make rain particle more thick in FSR 2.0? Or eliminate weird flickering lines on the edges of faraway structures with any other settings? I am just asking because visually i would love rain to be more appearant and thick altho its no big deal. Since the atmosphere is amazing anyway.
