Link to the public change log for more details.

The previous, alpha release included a number of other important improvements:

• 22% faster CUDA-accelerated DXT compressor
• Compiled/compatible with release NVIDIA CUDA Toolkit
• Added support for input DDS files, including cube maps
• Added support for input PSD files
• Added nvdecompress tool

Please visit our new developer forums to get support, share and discuss any suggestions or problems you may have.

12.5x faster and with higher-quality DXT compression than our previous version, our new GPU-accelerated Texture Tools support new DirectX 10 texture formats and come with complete source code.

The graph below shows the compression rate (in textures per second) across a range of popular high-quality compressors.  All compressors were running on one processor of an Intel Core 2 Duo X6800, and the texture size was 1,536 x 1,536.

Not all functionality of our previous texture tools has been ported to this new version.  The older tools are still available, but please note that they are not GPU-accelerated.
