Hey @jblackwell I work as a 3d artist in the automotive industry and I have to render in pathtrace for better results. And again this problem is not really fireflies. More flickering of the sun disc in reflective objects. Edges of the car or rim edges for example. And when I delete the anti aliasing part in the MRQ the flickering is completely gone. This is so strange… I am now on holiday when I come back I can share more screenshots that everyone knows more what I mean. Thanks for your help dude appreciate
