The Voodoo was the first 3D game accelerator to offer exceptional performance and quality. The RIVA 128 was scorned for its lower quality rendering (compared to the Voodoo) and rendering errors.<sup id="cite_ref-Peddie_5-1" class="reference"><a href="#cite_note-Peddie-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> </p><p>With initial drivers, the RIVA 128 used per-polygon <a href="/wiki/Mipmap" title="Mipmap">mipmapping</a> instead of the much higher-quality, but more demanding, per-pixel variety.<sup id="cite_ref-Peddie_5-2" class="reference"><a href="#cite_note-Peddie-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> This caused the different texture detail levels to "pop" into place as the player moved through a game and approached each polygon, instead of allowing a seamless, gradual per-pixel transition. Nvidia eventually released drivers that allowed a per-pixel mode. Another issue with the card's texturing was its use of automated mipmap generation. While this improves visual quality and performance in games without mipmaps, it also caused unforeseen problems because it forced games to render in a way that they were not programmed for. </p><p>NV3's bilinear filtering was actually "sharper" than that of 3Dfx Voodoo Graphics. But, while it did not blur textures as much as Voodoo, it did instead add some light noise to textures, because of a lower-fidelity filtering algorithm. There were also problems with noticeable seams between polygons. </p><p>While initial drivers did present these image-quality problems, later drivers offered image quality arguably matching that of Voodoo Graphics. In addition, because the RIVA 128 can render at resolutions higher than 640×480, the card can offer quality superior to that of Voodoo Graphics, as shown in the above <a href="/wiki/Quake_II" title="Quake II">Quake II</a> screenshot.
