Toggle the Chaos Telemetry. Check the  Chaos Telemetry  page for additional information. VRay CUDA GPU Device Select 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. Enable the desired render device by ticking the checkbox. We recommend in situations when the video memory of the graphics card is insufficient to use  only  the CPU as a rendering device. This way you will use the system RAM instead of the VRAM of the graphics card. You can also set CPU/GPU devices available for rendering outside of Unreal using the  vray_gpu_device_select  tool located in "C:\Program Files\Chaos Group\V-Ray\Unreal\ ools\vray_gpu_device_select.exe"  or you can use the shortcut from ІІStart MenuІІ> Programs>V-Ray for Unreal . This tool is useful when setting up CPU/GPU devices on render servers for distributed rendering. For more information on V-Ray and RTX graphic cards, see the  OptiX and NVLink FAQ  page.
