The compressors available in the NVIDIA Texture Tools are not designed for real-time compression. If you need to compress textures in real-time, I'd recommend to look at the following sources:
J.M.P. van Waveren was the first one to describe a [http://www.intel.com/cd/ids/developer/asmo-na/eng/dc/index.htm real-time DXT compressor]. This compressor is part of the of [http://softwarecommunity.intel.com/UserFiles/en-us/Image/1221/Real-Time%20Texture%20Streaming%20&%20Decompression.pdf real-time texture streaming pipeline] used in some [http://www.idsoftware.com Id Software] games.
