use reshade an activate TAA Shader this is the best option to get rid of that
ReShade with the following shaders active -
-TAA
-Adaptive sharpen
u can experiment with thos settings too:
-FocalDOF.FX
-PD80_04_Contrast_Brightness_Saturation.fx
-PD80_04_Selective_Color_v2.fx
-PPFX_Bloom.fx
-PPFX_Godrays.fx
-FXAA.fx
-HexLensFlare.fx
-Levels.fx
-MagicHDR.fx
first i would only use TAA and maybe adaptive sharpen just try
