Alright np, I helped and explained this already to another person having issue with ghosting. Same stuff applies here.
And some extra stuff. If you have a monitor above 1080p you can leave r.TemporalAA.Upscaling=1.(TAAU instead of TAA) Anything below 1080p that doesn’t look very good.
You can test between frameweight .3 to .255. 3 being the sharpest with just I tiny bit of flickering or .255 will most likely stop flickering but cause thin objects to look like Vaseline if poured on your screen.
If you are using TAAU. The lower your r.Screenpercentage, the lower frame weight is needed to stop flickering.
Look for an output velocity in your material.
