From PC Mag: AMD on Wednesday pulled back part of the curtain on FSR 2.0, the hotly anticipated upgrade of its FidelityFX Super Resolution spatial upscaler/supersampler (that distinction changes depending on the color of the logo).
FSR 2.0 promises to up your framerates for "free," as it were, the same promise made by competing technologies like Nvidia's deep-learning supersampling (DLSS). But which of these framerate-boosting techs will reign supreme? It's Big Green and Big Red, back at it again.
FSR 2.0, revealed as part of the annual Game Developers Conference, accomplishes this through "temporal upscaling," a technique that uses three different vector points in an image (provided to the algorithm by game developers) to upscale a downrendered image's sharpness and overall quality to appear as indistinguishable from native resolution as possible.
FSR 2.0, unlike DLSS 2.3, does not require any machine learning to train its algorithm. However its compatibility is a bit of a mess. What games, APIs, and graphics cards it will work with are all a matter of detail.
