Most new chips have a host of features built into hardware to improve performance and image quality.
The days where you have to trade features over performance are almost gone. Glide can be a better choice for games that support it, one of the reasons 3dfx had such a strong following among gamers. Luckily, most of the new games written to Glide also support the industry-standard Direct3D or OpenGL APIs. In fact, 3dfx has fallen somewhat behind in the feature race. The Voodoo3 also doesn't fully take advantage of AGP it must copy the entire texture into local memory, again limiting the size of the textures it can work with.
