This page offers a beginner's guide to GPU rendering with V-Ray.
What is V-Ray GPU?
V-Ray GPU is a render engine on its own. It is specifically designed to take advantage of your GPU device(s) to boost the speed and performance of the renderer. In addition, you can also use it in combination with your CPU device. This is the so called Hybrid rendering – when the V-Ray GPU engine performs raytracing calculations with the CPU, or simultaneously with both the CPU and GPU devices of your computer.
V-Ray GPU supports a variety of features and even more features are added with time. Although it shares the same user interface as the V-Ray engine, V-Ray GPU differs from the regular V-Ray engine in the way it performs certain calculations. Comparing the results of both engines will never come to a one-to-one match, although it may look quite close. Further, it is not the goal for them to be the same.
This is why, it is strongly recommended to not switch between engines in the middle of your project - if you start setting up a scene with the regular V-Ray engine, use it for the entire project. The interface will only show the available options and your scene will be optimized for GPU rendering.
V-Ray GPU can be used as a production render or in IPR mode to quickly preview scene changes. It also supports both the Progressive and Bucket Image Samplers.

What devices does V-Ray GPU support?
V-Ray GPU rendering is based on the NVIDIA CUDA and RTX platforms. V-Ray GPU is supported only in 64-bit builds of V-Ray for Maxwell-, Pascal-, Turing-, or Volta-based NVIDIA cards.
