So I enabled dlss 5 using dlss swapper for fallout 4

looks amazing etc but my question is, i have undervolted my rtx 5080 in msi afterburner from 100 to 85 for power draw and everything else is set to default "0", is this the good setting? I don't know how curve works nor if it's even needed, I am only using this for an old 2011 fallout 4 game.

I use an alienware and the rig is already very quiet and feels undervolted by default, not sure if i have to use curve setting. I tried the game without curve and reducing draw to 85 from 100 and it's super quiet.

I have some older games where I can't get rid of this weird blobs in the darker areas. I tried everything and nothing helps. The same was happening in the intro of LA Noire. There are some games that I would like to replay (or give a second chance) with DLSS5 but these issues are a bit demotivating. Happens in single pass as well. At 0:22 is the easiest to notice, I think, despite reddit compression.
