Epic Games have done a talk at SIGGRAPH 2017 and it turns out they're looking to make Vulkan the default API for exported Linux games.

The Epic Games presentation starts from 1:18:45. If you listen at 1:21:55 it's mentioned a few seconds later that Vulkan will be made the default for Linux.

Hopefully this will help the developers who've been having lots of issues with OpenGL in Unreal Engine, like EVERSPACE.

It sounds like Epic are actually putting quite a bit of focus on Vulkan, which is great. If you have access to their github, you can actually run the editor with Vulkan right now by passing "-vulkan" to it when you launch it.

And we were beginning to wonder if Epic had forsaken EU4 on Linux. But does this mean that all the current OpenGL issues (thinking of ARK, et al) will never get fixed?

Nice vote of confidence towards Vulkan API support for Linux.

HLSL support means less work for porting games from DirectX?

Very end of video, VR on GNU/Linux next week apparently.
I've yet to go over HLSL areas in more detail, will do so after work.

They still released Fortnite last week with only Win+Mac support. Do they have Metal support for that or is the OpenGL support actually good enough?

ARK devs already said that OpenGL won't be fixed and that they will switch to Vulkan for that. In ARK time of course.

Too bad they're not committing to Vulkan as the default on every platform that has support for it.

They would generate Vulkan shader language using HLSL thus decreasing time required for porting. Or I got it wrong :)

I think it's not quite that easy. There are API differences in using HLSL for DirectX vs Vulkan, but work is ongoing to help with that. So "it depends on the code" is probably the best thing to say, but I think it would at least help. I don't really work with it that much; these are just areas I would expect to need special consideration.

Wouldn't expect to see anything from this being done by porters for at least 6 months, if not longer. Just in case anyone was wondering.

That would be for Metal API, I don't know if there is an option to run openGL but I doubt it as they were building for Metal for more than a year.

They want a HLSL to SPIR-V compiler. IIRC, that is already being worked on by someone.
