Since Crocus was merged into mainline Mesa last week we have been looking at benchmarks of this new open-source Intel Gallium3D driver designed exclusively for older Intel graphics hardware (i965 Gen4 through Haswell Gen7, plus Cherrvyiew and experimental Gen8 Broadwell) compared to the existing open-source i965 classic driver. Prior articles have looked at the quite good performance with Haswell while Sandy Bridge is in somewhat rough shape. Today's testing is going in the middle and looking at the Crocus vs. i965 OpenGL driver performance for Ivy Bridge with the once great Core i7 3770K.

Last week Valve introduced Vulkan rendering support for Left 4 Dead 2. The L4D2 Vulkan support is similar to that of Portal 2 where DXVK is being leveraged for translating the Direct3D calls to Vulkan rather than relying on their OpenGL translations. For those wondering what this means for L4D2 performance on Linux with modern GPUs, here are some benchmarks of Left 4 Dead 2 when testing the OpenGL and Vulkan rendering options.
