You can find more information on supported features and known limitations as well as hardware and drive requirements for Arnold GPU on the Arnold documentation portal. Note that at this time, there are still some limitations to rendering with Arnold GPU.

The majority of lights are supported, including portals Most LPEs (39/46 and counting) are now supported GPU noise is now on par with CPU noise when using adaptive sampling, which has been improved to yield even faster, more predictable results regardless of the renderer used. Time to first pixel is now faster thanks to a number of improvements including more efficient NVIDIA OptiX cachingīounding volume hierarchy (BVH) memory used by geometry is reduced by as much as 50% for large meshesĪ first version of the new Shadow Matte shader has been added to the GPU rendererĮxcessive sources of noise have been removed, such as indirect noise in refractions or reflections. Textures are now loaded on-demand instead of at the start of the render, helping to reduce memory usage and save time from the first pixel

Improved support for Open Shading Language (OSL)
