I'm currently learning how to use Houdini and have a question regarding GPU rendering. I would like to know if it's possible to enable GPU rendering in the viewport. If so, could you please guide me on how to accomplish this?

I've been looking through the settings but I can't seem to find the appropriate options to enable GPU rendering specifically for the viewport.

Any help or guidance would be greatly appreciated. Thank you for your time.

Houdini is a huge Software, there are many Options and Details it takes a lot of time to understand it as a houdini beginner.

GPU rendering is under LOP's Solaris context as w_maro noted.

Rendering in viewport is also possible with mantra but it is EOL
