Khronos Group Announces Release of Vulkan 1.0 (phoronix.com)
An anonymous reader writes: Vulkan 1.0 was released this morning as a surprise for those looking towards a high-performance, cross-platform (everyone but Apple) API. In a lengthy overview of Vulkan 1.0, the stage is set for making Vulkan what it's been talked up to be, but it's not there yet for end-users to fully enjoy: NVIDIA has conformant drivers out for major platforms, AMD doesn't have any conformant driver yet, and Intel only has a conformant Linux driver. The lone launch title for Vulkan 1.0 is Talos Principle, but don't expect it to perform better than the OpenGL port at this time. While it's easy for many game developers to port to Vulkan, it will require significant investment to make the engines really much faster than their OpenGL/DirectX11-geared code-bases while new games should be much better from the start when designed around this lower-level API. The spec will be available at Khronos.org and the Vulkan SDK is available from LunarG.com. -
Valve Bootstrapped Source 2 Engine On an Open-Source Vulkan Driver
An anonymous reader writes A new article out details how Valve bootstrapped their VULKAN back-end with the Source 2 Engine over a period of just four months thanks to relying on an open-source driver. With designing for the open-source Intel Vulkan Linux driver developed by LunarG, Valve developers were quickly able to resolve issues and progress the driver in a turn-key manner. This Intel Linux driver will be released as open-source once the Khronos VULKAN specification has been published. -
Major Performance Improvement Discovered For Intel's GPU Linux Driver
An anonymous reader writes: LunarG, on contract with Valve Software, discovered a critical shortcoming with the open-source Intel Linux graphics driver that was handicapping the performance. A special bit wasn't being set by the Linux driver but was by the Windows driver, which when enabled is increasing the Linux performance in many games by now ~20%+, which should allow for a much more competitive showing between Intel OpenGL performance on Windows vs. Linux. However, the patch setting this bit isn't public yet as apparently it's breaking video acceleration in certain cases. -
Valve Sponsors Work To Greatly Speed-Up Linux OpenGL Game Load Times
An anonymous reader writes "Valve Software has sponsored some interesting improvements developed by LunarG for the Mesa OpenGL library on Linux for deferred and threaded GLSL shader compilation. What these changes mean for users of the open-source Linux graphics drivers when running their favorite games is that OpenGL games now load a lot faster. As an example, the time from starting Dota 2 until the time actually being within the game is reduced by about 20 seconds on an Intel system. While Direct3D has offered similar functionality for a while, OpenGL has not, which has given it a bad reputation with regard to game load times until all shaders are compiled and cached — fortunately it's now addressed for OpenGL if using the Mesa Linux graphics drivers on a supported game."
