AMD Releases FidelityFX Super Resolution FSR 2.1
FidelityFX FSR2 v2.1.0 is focused on improving the image quality and "significantly reducing" artifacts around ghosting and shimmering. FSR 2.1 remains API-compatible with FSR 2.0.
FSR 2.1 makes use of motion vector divergence to diminish locked pixels, improved disocculsuion logic, moving some half-precision operations to full-precision for better quality, reactive mask dilation and numerical range improvements, composition and transparency mask updates, and more.
