The discussion centers on the visual differences in LaTeX rendering between two users, hellfire and Tipi. Hellfire's LaTeX appears smoother and softer, while Tipi's is described as more jagged. Users note that the primary difference is that Tipi's equations are centered, whereas hellfire's are not. The smoother appearance is attributed to potential differences in internal rendering settings, possibly related to the LaTeX generator used at the time of posting. Hellfire's post, dated 2005, utilized an older, more resource-intensive LaTeX engine, while the current engine in use is MimeTeX. The conversation suggests that the rendering quality may not be a special feature for select members but rather a result of changes in the LaTeX rendering system over time.
