1. A multi-mode texture decompression method for use during graphics processing, comprising;

  • (a) sending a request for compressed texture data to memory;

    (b) receiving the compressed texture data from the memory;

    (c) identifying at least one of a plurality of compression algorithms associated with the compressed texture data; and

    (d) decompressing the compressed texture data in accordance with the identified compression algorithm;

    wherein, prior to sending the request, the texture data is compressed utilizing each of the plurality of compression algorithms, the most favorable compressed texture data is selected utilizing a comparison operation, and the most favorable compressed texture data is stored in the memory;

    wherein the most favorable compressed texture data provides the most accurate replication of an original version of the texture data.
