Release Highlights NVIDIA® OptiX™ 7.6 (October 2022)

The OptiX 7.6 SDK adds support for Opacity Micromaps (OMMs) which provide hardware accelerated alpha mask checks for triangle mesh geometry. OptiX 7.6 OMMs leverage the new Ada Lovelace generation of GPUs to provide hardware acceleration of OMMs, while previous generations are supported through an optimized software implementation.
