Hardware raytracing

This article or section needs expansion.

Reason: This article needs feedback from users with compatible Intel & AMD hardware to expand its scope and accuracy (Discuss in Talk:Hardware raytracing)

This page will serve as a guide to the current state of Hardware raytracing support on Linux as well as provide information on how to set everything up.

In all cases it is assumed you will be running the game through Proton, VKD3D is required, DXVK will not work.

Note: Using raytracing requires that you set some environment variables, these can be set globally or per user.


AMD RDNA2 GPUs offer hardware raytracing support through onboard compute units, current performance is mixed. Since mesa 23, raytracing is enabled on a per game basis, and from mesa 23.2 raytracing will be enabled by default for all applications.


For mesa versions below 23.2, use the following environment variables:



Intel ARC GPUs offer hardware raytracying support through onboard TSUs, current performance is mixed.


Use the following environment variables:



NVIDIA's raytracing implementation for Linux is pretty much on par with Windows, that is to say, with supported hardware and the correct drivers RTX works well on Linux.

  • GPU - Any card with the RTX moniker (RTX 2060+, RTX 3050+, RTX 4050+)
  • Driver - nvidia 510.60.02 or newer with nvidia-utils and nvidia-settings (with their lib32 variants)


Use the following environment variables:

Note: This configuration will enable support for both Deep Learning Super Sampling and RTX.


Install the package raytracinginvulkan-gitAUR then from a terminal run:

$ cd /opt/raytracinginvulkan/bin/
$ ./RayTracer
