You know that all rendering is "a hack". It's all built around short cuts and approximations. The whole aim is to get the best looking result for a silicon/power/money budget. AI up scaling is the latest and greatest "hack" for doing that and as we have seen in games like Control, Wolfenstein and Minecraft it can work really well.Dlss is a tensor infused hack and in no sense the way forward. Going down in iq can never be the aim of the goal. But you were skimming the surface of something launching with DX 12.1! VRS, portions of the screen gets shaded way less. And you can pinpoint places on screen not needing per pixel shading and apply / not apply the same process on four pixels instead of one.
Upscaling is dead from the start though. I hope Nvidia quits this nonsense dinner than later.
