RADV Vulkan Driver Making Progress On Portal RTX Support

Mesa's Radeon Vulkan "RADV" driver is making progress on being able to run the new Portal RTX game.

Last week Portal RTX was released by NVIDIA Lightspeed Studios as a DLC to Valve's highly acclaimed Portal that adds ray-tracing. Portal RTX makes use of ray-tracing and also features new high resolution physically-based textures. Portal RTX for now at least is Windows-only but can run on Linux systems by way of Steam Play (Proton).

With Portal RTX being developed by NVIDIA's Lightspeed Studios, to little surprise it's focused on running on the latest NVIDIA GeForce RTX graphics cards. But for those using AMD Radeon GPUs with the popular Mesa RADV driver, there are steps being done to enjoy ray-traced Portal there too. But there's still work left.


Being merged yesterday were RADV and NIR fixes that at least get Portal RTX to the point of being able to reach the game's main menu... But you can't yet enjoy the game. This follows an earlier merge of fixes for Unreal Engine 4 and Portal with RTX RT shaders for RADV.

So Portal RTX isn't yet working for RADV, but for those that have been wondering, progress is being made by open-source developers. Hopefully by the release of Mesa 23.0 next quarter we'll see Portal RTX running with grace on Radeon GPUs under Linux with RADV.
