Texture formats

Texture decoding / sampling

The textures are sampled by the texture shader portion of NV2A/Pixel_Combiner.

Texture signedness

Each component of the texture can be either signed (two's-complement) or unsigned.[1][FIXME].

Texture filtering

The GPU implements the standard texture filters as known from OpenGL. In addition, it supports convolution filters[2][FIXME].

Framebuffer formats
