According to Phoronix, Alex Smith of Feral Interactive has just published a few changes to the open source Intel graphics driver, which allows their upcoming Dawn of War III port for Linux to render correctly on Vulkan. This means that the open-source Intel driver should support the game on day one, although drawing correctly and drawing efficiently could be two very different things — or maybe not, we’ll see.
It’s interesting seeing things go in the other direction. Normally, graphics engineers parachute in to high-end developers and help them make the most of their software for each respective, proprietary graphics driver. In this case, we’re seeing the game studios pushing fixes to the graphics vendors, because that’s how open source rolls. It will be interesting to do a pros and cons comparison of each system one day, especially if cross-pollination results from it.
