Wasting time? I don´t get it, when AMD advertised Async Compute, Primitive Shaders, etc, many people had an orgasm. But now with Nvidia, with tech that will be the future of gaming, it's a waste of time!
Above all, Nvidia is trying to propel the industry forward with new technologies and more efficient ways of extracting performance! It's not the simple core increase, clock increase, to continue to give more frames!
Of course it will not be immediate, this is just the beginning, but no doubt that this will be the future of gaming. The trade-off for now is the price. Next year, with the density of 7nm, maybe it allow smaller and cheaper chips.
One part that I found very interesting, is using the Tensor Cores for anti-aliasing (DLSS), which in theory can lead to minimal or nonexistent losses, than the others AA methods.
It would indeed be something fantastic, if we can have AA in its splendor without loss of performance. The demo of UE4 they showed at 4K with AA, the 1080Ti can only run it at 30fps and the RTX with the Tensor Cores, ran it at 73fps or 78fps.
