Multi-GPU

SettingDescription
Multi-GPU Enables the use of multiple GPUs in path-traced mode (when these are available and enabled at startup)Multi-GPU must be enabled at startup by passing adding -/renderer/multiGpu/enabled=true to the command line
GPU 0 Weight The amount of total Path-Tracing work (between 0 and 1) to be performed by the first GPU in a Multi-GPU configuration. A value of 1 means the first GPU will perform the same amount of work assigned to any other GPU
Compress Radiance Enables lossy compression of per-pixel output radiance values
Compress Albedo Enables lossy compression of per-pixel output albedo values (needed by OptiX denoiser)
Compress Normals Enables lossy compression of per-pixel output normal values (needed by OptiX denoiser)
