Zluda 6 release (run unmodified CUDA applications on non-Nvidia GPUs)

ZLUDA Version 6 has been released, enabling unmodified CUDA applications to run on non-NVIDIA GPUs with significant new capabilities including PhysX support for older games, Blender texture support, and improved Windows compatibility. The update also includes better machine learning support through compiler fixes and new instruction implementations, while maintaining ZLUDA's continuous development model where major releases signal substantial progress rather than specific features.
