The latest version of CUDA, version 4.1 RC2 is now available for download on NVIDIA's CUDA Zone for all developers.

Until now it was only for CUDA registered developers, but this morning the binaries were posted for public access.

This new release three major improvements:

• A new LLVM based compiler, which could give a 10% performance boost just by re-compiling
• over 1000 new image processing functions in the NPP library
• A new visual profiler with some powerful new functions.
