Maximize Performance of Nvidia’s Iray Render Time

Maxwell GPUs/Windows 10 performance improvement

The Iray Development Blog recently posted this information regarding iRay render times and setting for users with particular hardware.

If your machine contains Maxwell generation CUDA cards (like a MX000 or a GeForce 9XX) and you’re on Windows 10, please make sure that you have all the latest Windows 10 updates installed (especially the “Anniversary Update” needs to be there, build 1607 (from August 2016) and up) and that you also install a recent NVIDIA driver (378.XX).

The latter will add a new option to the NVIDIA control panel: “Optimize for Compute Performance”. Make sure to set this to on, either globally (if you do not play games on that machine and also do not have other high-end GL or DX things running), or for the applications only that include Iray (like 3Ds Max, Maya, Catia, Rhino, Daz3D).

Especially for complex scenes this can make a huge difference and finally brings the performance of Windows 10 on Maxwell on par with Windows 7.
