Portal Stories: Mel, an extremely popular and highly rated mod for Portal 2 just had a new Beta pushed out which adds in Vulkan support for Linux. Much like the update for Portal 2 that recently added Vulkan support, it's using a special native build of DXVK, the Vulkan-based translation layer for Direct3D 9/10/11.
Compared with the Portal 2 update, in some of my own testing today it seems that Portal Stories: Mel seems to benefit from the Vulkan upgrade quite a bit more in some places. At times giving a full 100FPS increase! So for those on weaker cards, this will probably be an ideal upgrade. Another game to test with Vulkan is always great too.
To run Portal Stories: Mel with Vulkan, you need to add "-vulkan" as a launch option, after opting into the Beta test. To opt into the Beta you need to right click on the game in your Steam Library, go to Properties, select Betas on the left list of options and then select "beta - Public beta branch" from the drop-down box.
Here's what's changed in the Beta overall:
- Fixed lighting issues with modern AMD GPUs.
- Added Vulkan support for the Linux build.
- Fixed wrong icon showing up on windows.
- Removed confirmation prompts for graphics settings.
