The hybrid render engine running on a CPU supports the same features as the regular V-Ray GPU CUDA engine. Meaning, this mode can be used on computers that don't even have GPUs. Furthermore, you can use the CPU as a CUDA device even if you don't have an NVIDIA GPU and/or NVIDIA drivers installed. The hybrid rendering mode does not require any special drivers. To enable the hybrid rendering mode, simply enable the C++/CPU device from the list of GPU devices. V-Ray can now execute the CUDA source on the CPU, as though the CPU was another CUDA device. Starting in 3.60, V-Ray GPU can perform hybrid rendering with the CUDA engine utilizing both the CPU and NVIDIA GPUs. Hybrid Rendering with CPUs and the CUDA Engine Turn on the statistics display to check the difference in render speed and to find the optimal settings for your system.

However note, that this will reduce the rendering speed. For example, you can try values like 64/1 or 32/1. This will break up the data passed to the GPU into smaller chunks so that the user interface requests can be processed faster. To alleviate this problem, reduce the GPU Rays per pixel and/or the GPU Ray bundle size parameters in the Interactive render settings. If you have only one GPU on your system, you may find that the user interface becomes sluggish and unresponsive while Interactive is rendering on the GPU.
