Hi there, still very new to Unreal Engine and I am a bit confused / annoyed with the blur behind my moving character. I am Using a fresh top-down project template and i did disable motion blur in the project settings. I can live with very lowpoly graphics, blurriness however I dislike with a passion.
Every AA method has its pros and cons, described on the UE documentation site as well. TXAA can flicker on moving objects but FXAA blurs the entire screen. You might want to use a sharpen filter on FXAA depending on your result, it can be quite noticable. In many modern games turning it off entirely actually looks great, it can depend on what other graphics enhancements you are implementing.
