This page provides information on the V-Ray GPU Render Devices Select rollout.


Overview

This rollout allows you to choose the devices for GPU Rendering. Selecting the GPU devices from this rollout is equivalent to using the external Select devices for V-Ray GPU Rendering utility that is included with V-Ray (ocldeviceselect.exe) but allows the devices to be changed without restarting 3ds Max.


With V-Ray 7, RTX engine can be enabled with V-Ray GPU engine select located in ||Render Setup window|| > Settings tab > V-Ray GPU Engine Select rollout (Renderer set to V-Ray GPU).



UI Path: ||Render Setup window|| >  Performance tab > V-Ray GPU Render Devices Select rollout (Renderer set to V-Ray GPU)

Parameters

With V-Ray 7, the default scene setting is CUDA.

Selecting specific devices to render with can help 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 for Hybrid Rendering.

Rendering – Selects GPU device or CPU for rendering.

Denoising – Selects GPU device for denoising.

Show more – Displays the log messages.

When multiple devices are selected for denoising, out of all the devices that match the query only the device with the highest compute capability is used for the denoising process.

The asterisk (*) sign next to a GPU device's name in the list means that a monitor is connected to that GPU device. If two or more monitors are connected to the GPU device, there are 2 or more asterisks next to the GPU device name.

There is a tooltip that appears upon hovering over the asterisks that shows information on the GPU and number of monitors connected to it.
