We just released OptiX 7!
OptiX 7 introduces a new low-level CUDA-centric API giving application developers direct control of memory, compilation, and launches while maintaining the programming model and shader types.
Please note that the OptiX 7 API is not backwards compatible with OptiX 6.5 or earlier. You will also need an NVIDIA driver numbered 435 or higher to begin using OptiX 7.
