  • Optimizing VRay RT

    Hi gang;

    When it comes to optimizing VRay RT GPU, what settings would provide the most speed gains?

    For example, does reducing the number of global illumination bounces affect speed? Are there any other key factors that can help optimize VRay RT GPU?

    Regards,

    Reducing the GI bounces and the trace depth would definitely speed things up. Using the light cache as a secondary engine will also give a speed boost (you might need to up the settings a bit for animation). Using a higher noise threshold and then denoising could be another option.

      In addition to Vlado's comments, two things I have done are:

      1. Overclock the GPUs for faster rendering. Use something like the EVGA Precision software and experiment until you can get speed increases while retaining GPU stability. I think I got ~10% rendering speed increase with this method but of course YMMV.

      2. Play around with the Rays Per Pixel and Rays Bundle Size numbers and see if you can increase performance this way. This would be especially true if you were using DR and outboard GPU rendering nodes.

      Oh yeah, decreasing Trace Depth might help as well - if you can afford it in your scene. Also, overclocking my i7 5960x and using hybrid GPU rendering also helped.

      Best of luck,
