Nvidia has confirmed that the new DLSS 5 algorithm is redrawing games based on a 2D image input and motion data. That's not great!
NVIDIA confirms DLSS 5 uses 2D frames and motion vectors, not full 3D data, raising questions about accuracy and control.
Other than taking into account motion vectors, it seems like there's not much more to Nvidia DLSS 5 than an AI rework of the final frame.
