The more technically minded among you might find this interesting.
Its about this thing you may have heard of, something CIG call "Gen12"
The problem with DX11 is most of the Draw Calls, that's the communication between the CPU and GPU is done through a single CPU thread, or core, the "Main Render Thread" this is primary cause of CPU bottlenecks is any game that runs DX11 or older, this is where your CPU's core running that Main Render Thread is not fast enough to keep up with the GPU, so the GPU needs to wait on it, the result of that is lower performance than your GPU is capable of, you can see it in action, for example if your GPU is only running at 70% that's a bottleneck cause likely by your CPU not being fast enough through the Main Thread to feed the GPU.
This is not so much of a problem with the CPU, all modern CPU's have multiple cores, but its running in to ancient Microsoft technology that's only programmed to use one of those cores.
This was such a problem, AMD thought that they should do something about it, they created their own competitor API, which they called Mantle, way back in 2014, its was launched with Battlefield 4. below is a video, its a comparison between DX11 on the left and Mantle on the right, notice there is up to a 2X performance difference.
That API is now managed by the The Khronos Group, AMD gave it to them as an independent entity so that competitors like Nvidia and Intel would feel comfortable adopting it, its now called Vulkan.
Since then Microsoft have hit back with DX12, which is still not as good.
Anyway, i digress. As a temporary measure, CIG are working on converting the game to Vulkan, they have created propitiatory code to optimise the Main Render Thread, Gen12, you wont necessarily see a difference in performance, because your CPU might be fast enough without it, however CIG have given you a way to measure it.
How that's done is you measure the render time of the main render thread, in milliseconds, if you type r_displayinfo 3 in to the console you can see it. The lower that render time the faster it is.
The second video below explains that with Gen12 enabled vs disabled, which you can also do in the console.
DX11 vs Mantle.
About Gen12 and testing.
