Valve unveiled Source 2, a more powerful engine for developers, at GDC.
"The value of a platform like the PC is how much it increases the productivity of those who use the platform," Stelly said. "With Source 2, our focus is increasing creator productivity. Given how important user generated content is becoming, Source 2 is designed not for just the professional developer, but enabling gamers themselves to participate in the creation and development of their favorite games. We will be making Source 2 available for free to content developers."
Vulkan, formerly known as Next Generation OpenGL, is a "cross-platform, cross-vendor 3D graphics API that allows game developers to get the most out of the latest graphics hardware."
"This combined with recent announcements by Epic and Unity will help continue the PC's dominance as the premiere content authoring platform," Stelly said.
