  • More AMD FreeSync Patches Likely Coming To Linux 5.2
    While the Linux 5.0 kernel brought initial support for the long-awaited open-source FreeSync implementation, the Linux 5.2 kernel coming out this summer will likely have additional improvements.  Open-source developer Mario Kleiner has been working on a set of patches this month for enabling proper vblank and page-flip time-stamping when in the FreeSync/VRR (Variable Rate Refresh) mode. This work makes the vblank timestamps as accurate as in the fixed refresh rate behavior. 
  • Primus-VK: PRIME-Style GPU Offloading For Vulkan
    For those with a PRIME style notebook or just making use of dual/multiple graphics processors in your system, Primus-VK allows for using a secondary/dedicated GPU for rendering while driving the display from the alternative (often integrated graphics) GPU. Primus-VK is implemented as a Vulkan layer as a clean approach for dealing with multiple GPUs in a Vulkan world.  Primus-VK pursues Vulkan GPU offloading by implementing this logic as a Vulkan layer for handling the rendering on one GPU and then when it comes to display-time it copies the image over to the integrated/primary GPU. This layer can be installed per-user or system-wide and has been tested on the likes of Debian. ENABLE_OPTIMUS_LAYER=1 is the environment variable used for activating the behavior. Primus-VK has also been tested with Windows games under Wine.
  • NVIDIA Releases Nsight Graphics 2019.2 With Vulkan Profiling Support
    Released for GDC/GTC week was Nsight Graphics 2019.2, the proprietary cross-platform, closed-source utility tool for debugging, profiling, and analyzing Direct3D, OpenGL, and other GPU-accelerated APIs.  With this week's Nsight Graphics 2019.2 release they finally have added Vulkan profiling support. This support allows inspecting GPU performance metrics under Vulkan workloads within the program's Range Profiler. Other new additions include improvements for running Steam games on Linux, a feedback button, and enhancements to the accelerated structure viewer and API inspector.
