Footnotes

...

Anchor
1
1

 1 – Displacement results between CPU and GPU rendering may differ slightly because of Pre-tessellation and Cache Normal settings.

Anchor
2
2

2 2 – GPU always uses raytraced multiple scattering for VRayFastSSS2. V-Ray GPU Single Scatter is supported only in None and Simple modes.

Anchor
3
3

3 – Using Light Cache (as a secondary GI engine) with GPU is possible only when used in Production rendering mode. In IPR  IPR mode, Brute Force is used as the primary and secondary engines for both GPU and CPU.

Anchor
4
4

4 – – Irradiance map loaded from a file is supported in GPU only in Production rendering mode.  In IPR mode, Brute Force is used as the primary and secondary engines for both GPU and CPU. Anchor555 – Photon map can be used for Production rendering on the CPU. In IPR mode, Brute Force is used as the primary and secondary engines for both GPU and CPU.

Anchor
6
6

6 5 – IPR rendering supports motion blurred frames on integer numbers only. For example, starting the render from frame 1 will produce correct motion blur, but starting from frame 1.25 will produce incorrect motion blur. Anchor777 – The Global max depth override can be used for Production rendering on the CPU. RT uses its own parameter - Trace Depth that is found in the RT Tab of the Render Settings window.

Anchor
8

8 6 – IPR GPU does not support the "Multiply by front diffuse" option of the 2SidedMtl.

Anchor

97 –  IPR rendering does not support BRDFAlSurface shader.
