DLSS4 Transformer is what engineers envisioned for TAA but never achieved.
DLSS 4 transformer has PERFECT (literally perfect) anti aliasing and 90% perfect in movement. Even TAA struggles to remove aliasing without blurring out the image in a still scenario. I'm using 1440p right now and I can't find a single jaggy that is not explained by the 3.8 million pixel limit. The only thing left to improve is the slight smearing that remains and eventually start making it more efficient if possible. (more fps for same quality)
