This article reviews major GPU text rendering approaches, from bitmap texture atlases to signed distance fields (SDF), multi-channel SDF (MSDF), and Slug. It explains the tradeoffs in sharpness, scaling, memory use, and support for dynamic text, and highlights Slug as a direct-outline rendering technique now available in the public domain.
