Path Tracing in Game Activation Unreal 5.6

Hi,

We’re running some tests with Unreal Engine 5.6 and have a question. We activate path tracing in-game by pressing the T key, as you can see in the screenshot.

It’s great that users can switch between path tracing and Lumen depending on the level of accuracy they need.

Path tracing has become really fast, but is there a way to make it even quicker? Which values, or techniques should we explore to reduce the time it takes to compute each pixel?

Thank you in advance for your help.

You can control the pathtracing parameters in a post process volume. Max bounces and samples per pixel are some things to mess with to get the times down but it will be at the cost of quality.
