Hello! I want to experimentally compare the performance of hardware-accelerated ray tracing based on RT cores and ray tracing relying on CUDA cores. Which version of legacy OptiX should I use for ray tracing that relies on CUDA cores? Could you give me a sample program with the corresponding version as a reference?
Any suggestions are appreciated. Thank you in advance.
Hi @thiltuiv,
OptiX versions before 6 don’t support RT cores.
A simple test is to compare the framerates of two “equivalent” programs e.g. the path tracer.
Be careful comparing apples to apples (max. bounces and num. samples in particular).

Using a very old version of optix will introduce many more differences than RTcores on/off. For instance, older versions can use completely different acceleration structures and traversal algorithms.
