NVIDIA Picture Scaling Restricted to DX11 GPUs, Not for Vulkan/OpenGL as is, In contrast to AMD FSR

Some fascinating information about NVIDIA’s newly open-sourced Picture Scaling expertise have come to mild. In response to customers on the Phoronix boards, in contrast to AMD’s FSR spatial upscaler, NVIDIA’s NIS is a D3D compute shader (FSR is a generic HLSL/GLSL shader suitable with any API and {hardware}) restricted to DX11+ suitable video games and techniques. Moreover, NIS is way more summary and high-level in comparison with FSR which makes it laborious to customise and tweak relying upon the sport.

NVIDIA’s Picture Upscaler additionally seems to be a easy single-pass shader whereby upscaling and sharpening are each accomplished throughout the identical cross. AMD’s FSR, however, makes use of separate passes for every, making it a extra intricate shader. The truth that NIS isn’t transportable to Vulkan or OpenGL signifies that it might’t be used on titles utilizing some other API aside from DX11+, rendering it ineffective for Linux and non-Home windows platforms. In the long run, NIS seems to be a PR stunt greater than anything, attempting to undermine AMD’s promise that FSR will run on “nearly any PC”.
