Nvidia Unleased the Power of Tensor Cores and their Saturn V supercomputers for AI and Deep Learming in DLSS 2.0. The major difference between DLSS 1.0 and DLSS 2.0 - In Short:
125% Increase in Fps and requires 400% zoom to see the difference and some times better than Native Rsolution
Remove the expensive per-game training and the many (many) problems that non-deterministic games presented in training, NVIDIA has moved to a single generic network for all games.
This newer neural network is based on a fully synthetic training set rather than individual games, which in turn is fully deterministic, allowing NVIDIA to extensively train the new network in exactly fashion they need for it to iterate and improve over generations.
