Hello try the following commands:
r.MotionBlurQuality 4
r.MotionBlurSeparable 1
r.DepthOfFieldQuality 4
r.ForceLOD 0
r.TemporalAA.Upsampling 0
foliage.ForceLOD 0
Also have in mind there is a bunch of possible causes, for example the Current Aperture of the camera perhaps is too low:
If I increase:
Another possible reason is the material is using embed alpha instead a proper independent opacity map, which causes it loads twice the texture, or configuration itself is not good:
Hope it helps!
