AMD will soon be releasing the company's newest super-resolution upscaling technology, FidelityFX Super Resolution or FSR 2.0, an AI-algorithmic-less temporal upscale that will go head-to-head with NVIDIA DLSS with Tensor Core technology. NVIDIA's technology uses AI to enhance the acceleration of the graphics on the user's system. TechPowerUP uploaded their world premiere review of the new AMD upscale technology, and the reviews sound very promising for gamers.

The first version of the AMD FidelityFX Super Resolution upscaler incorporated spatial techniques compared to the new 2.0 version, which uses temporal upscaling and integrates motion vectors, among other graphical methods. The benefit of spatial upscaling versus temporal techniques was that the original FSR was easier for game developers to incorporate into their titles. With the new FSR 2.0, the upscaling is more complex and requires developers to note the latest changes, but the company promises the output is worth the time spent.
