Recently, NVIDIA worked with Epic to integrate Adaptive Temporal Antialiasing (ATAA) into Unreal Engine 4. This new approach solves for the weakness of TAA (temporal anti-aliasing) - blurring and ghosting artifacts - while remaining light enough to avoid introducing a significant performance hit. ATAA results are remarkably close to what a developer would achieve through 16x supersampling, with operations that fall within a 16ms frame budget.
