### **Notes**

- V-Ray GPU works only with **C++/CPU** devices under macOS. V-Ray GPU can still be used in distributed rendering where a macOS machine runs the CUDA engine on a CPU device together with **Windows**/**Linux** machine(s) running CUDA engine on GPU device(s).
- The Qt6 framework is only supported for Houdini 21 V-Ray builds.
- For information on hardware, see the [Hardware Recommendations](https://support.chaos.com/hc/en-us/articles/4406890478865-Hardware-Recommendations) article.
