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 CUDA devices. V-Ray can now execute the CUDA source on the CPU, as though the CPU was another CUDA device. 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. Note, however, that this reduces the rendering speed. This breaks up the data passed to the GPU into smaller chunks so that the user interface requests can be processed faster. For example, you can try values like 64/1 or 32/1. To alleviate this problem, reduce the Rays per pixel and/or the Ray bundle size parameters in the Performance tab of the V-Ray GPU renderer settings. If you have only one GPU on your system, you may find that the user interface becomes sluggish and unresponsive while V-Ray GPU is rendering.

If the V-Ray GPU render server is running as a Windows service, you may need to stop it from the Services applet in the Control Panel. To do this, you can use the control in the V-Ray GPU Render Devices Select in 3ds Max, which allows you to specify which devices you want to use for GPU rendering.Īlternatively, you can use the supplied GUI tool, which you can find in Start Menu > Programs > V-Ray 5.0 for 3ds Max > Select rendering devices for V-Ray GPU 5.0 for 3ds Max.Īfter changing this option, you need to restart the 3ds Max (or V-Ray Standalone) if it is running for the changes to take effect.

You may not want to use all available GPU devices for rendering, especially if you have multiple GPUs and you want to leave one of them free for working on the user interface or you may want to combine your CPU and GPU together (see the Hybrid Rendering section below). Also note that to prevent performance loss, not all data is shared between devices.Ĭhoosing Which Devices to Use for Rendering For GeForce RTX cards, a SLI setup is sufficient. This is recommended for Pascal, Volta and Turning-based Quadro models. To use NVLINK on supported hardware, NVLINK devices must be set to TCC mode.
