Vigile writes: One of the concerns surrounding the recent debate of the Unified Windows Platform and games being released on it, such as the recent Gears of War Ultimate Edition, was the inability for media and consumers, and even entry level developers, to properly profile the performance of those applications. All of the standard testing applications like Fraps, FCAT and other overlays are locked out of UWP games. A Intel graphics engineer released a tool called PresentMon on GitHub yesterday that accesses event timers in Windows to monitor Present commands in any API, including DX11, DX12, Vulkan as well as games built on the Windows Store platform. Using this data, PC Perspective was able to profile the performance of the new Gears of War on PC, comparing frame time variability between the two flagship parts from NVIDIA and AMD. While it's not a perfect utility yet, there is hope now that this open source code will allow for performance metrics on any and all gaming titles.
