ADVANCING THE STATE-OF-THE-ART
GeForce GTX 980 Whitepaper IN IMAGE QUALITY
NVIDIA engineers have recently developed new AA algorithms that vary, in interleaved fashion, the
sample patterns used per pixel either spatially in a single frame (where, for example, each successive
pixel uses one of four different 4xAA sample patterns) or interleaved across multiple frames in time.
Multi-Frame Sampled AA (MFAA) is a new AA technique that alternates AA sample patterns both
temporally and spatially to produce the best image quality while still offering a performance advantage
compared to traditional MSAA. The final result can deliver image quality approaching that of 8xAA at
roughly the cost of 4xAA, or 4xAA quality at roughly the cost of 2xAA.
MFAA is still under development. We'll provide more details on the technology once we get closer to
release.
