Since the disastrous launch of the RTX 50 series, NVIDIA has been unable to escape negative headlines: scalper bots are snatching GPUs away from consumers before official sales even begin, power connectors continue to melt, with no fix in sight, marketing is becoming increasingly deceptive, GPUs are missing processing units when they leave the factory, and the drivers, for which NVIDIA has always been praised, are currently falling apart. And to top it all off, NVIDIA is becoming increasingly insistent that media push a certain narrative when reporting on their hardware.
That’s essentially an emulation layer. Nvidia make DLSS specifically for their GPUs, which have CUDA cores on them. It’s the reason why DLSS doesn’t work on their pre-CUDA core hardware.
Could they make DLSS work on AMDs hardware? Sure, they could - but it would not be DLSS as we know it, and again - why would they? They are allowed to make stuff exclusively for their hardware.
