Valve Developed Own Vulkan Driver For Intel, They Demo Dota 2 On Source 2

Posted by , | Views: 16,585
Valve have been extremely busy, and we are already seeing some fruits of their work. They have written a Vulkan driver for an Intel GPU, showed Source 2 with Dota 2 on it, and they will open source the driver.

It’s fantastic that Source 2 is getting in on the action so early! They even have a video of it running:

Thanks to PC Perspective for the video

You can see a slide below outlining a few interesting points:

Major thanks to SteamDB for being there and for their live blogging.

I really, badly, hope that Nvidia, AMD and Intel buckle down and get on it. It isn’t just Steam Machines and SteamOS that will push us to succeed, as we need this Vulkan API to bring the performance we have been lacking often.

There is also this video of a debugger called GLAVE developed by Valve and LunarG:

It’s worth noting that the Vulkan API has not yet been finalised, and we imagine we will hear more and more about it as the year goes on.

Yea, valve can take all my money + all my deposits and savings in the bank!

The slide says "Vulcan supported ACROSS THE BOARD on Steam Machines". I assume this means both AMD and nVidia have Vulcan drivers for Linux in development.

I have already feared that some guys from this site go nuts back on Tuesday!

Valve doesn't only make promise after promise, they are really working hard and delivering high performance.

All the Vulkan stuff has been the best news to come out of GDC really. If they can get this out soon (before DirectX), redudce driver overhead and make it easier for developers then it's fantastic news for us.

Btw, does anyone know if this will work on PS4 instead of OpenGL or not? That's going to be a pretty big factor in its adoption.

PS4 dont use OpenGL, them use own lenguage pssl (PlayStation Shading Language)

Maybe this document expain more about that (around 50 pages)

My plums are tingling. Guys, we're just gonna keep getting more and more epic news as the year rolls by.

Segata SanshiroBtw, does anyone know if this will work on PS4 instead of OpenGL or not? That's going to be a pretty big factor in its adoption.

AFAIK, Sony's API implementation is low-level as well....so i'm unsure if Vulkan will help them very much.

I always thought they used a slightly modified version of OpenGL and a slightly modified BSD as the OS... Maybe I'm thinking of the PS3 or maybe I just made that up completely. Whoops!

You're just about right. Both the PS3 and PS4 are based of modified versions of FreeBSD. The PS4 features two graphics APIs; a low-level API called GNM and a high level API called GNMX. (Sony also uses their own PlayStation Shader Language (PSSL), specifically introduced with the PS4).

The PS3 uses PSGL (which is a mix of OpenGL ES and NVIDIA's CG).
