Graphics performance is a common motivation when choosing vertex markers over normal markers. In both cases, the glyph can be customized to achieve the desired effect.

One important decision is to use a glyph that is hardware accelerated since not all glyphs will result in the high performance you are expecting. The following glyphs provide hardware acceleration:

- HPS::Glyph::Default::Dot
- HPS::Glyph::Default::SolidBox
- HPS::Glyph::Default::SolidCircle

For 10,000+ markers, the rendering speed can be drastically improved when using a hardware accelerated glyph.
