When Low priority is enabled, V-Ray tries to lessen the load on GPUs working on displaying graphics to the monitor(s) in order to give them more resources to complete other processes and tasks for the OS.
It can also set Low GPU Thread Priority per device. The Select devices for V-Ray rendering tool also allows for selecting GPU devices for denoising. 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 without restarting 3ds Max.Īlternatively, you can use the supplied GUI tool, which you can find in Start Menu > Programs > V-Ray 6 for 3ds Max # > Select rendering devices for V-Ray GPU for 3ds Max #, where # is the 3ds Max version.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.
