What setting changes the light splotches?

[TAKYON]

When something moves it recalculates the lighting behind it, but it's averaged over a few frames and it causes like a haze behind things, makes it really hard to see dark hunters because i don't know if it's just the splotches or a hunter

Could it be the ghosting effect that is caused by upscaling with dlss or fsr?

[TAKYON]

not using upscaling or frame interp, could be TAA but there isn't a good alternative AA method.
it's related to global illumination, but setting GI, lighting and shadows to highest still has the problem

[TAKYON]

turning on FSR and changing global illumination/lighting to lowest and highest. no combination seems to be able to make it go away
