Serious Sam versus the evil V-Sync latency

With the help of OCAT and PresentMon, OCC have taken a serious look into the effect V-Sync has on latency in a variety of scenarios.  They chose to use Serious Sam as the platform to test the differences various methods of applying V-Syn have on the performance of a GTX 1080 and Vega 64.  Windows 10 also offers a challenge, as you now have to be aware if you are playing a game in proper fullscreen or as a borderless window.  This all adds up to a long article, but is also perfect to demonstrate the best way to ensure gaming without any tearing.

"I am not completely sure if a conclusion is really necessary for this article, but why not? As is perhaps not surprising, playing in a Borderless window under DirectX 11 results in the highest frame latency, because of omnipresent Desktop Window Manager's double buffering."

Here are some more Display articles from around the web:

Why they run V-Sync latency tests on a crap AMD A10 CPU? and why 6 month old driver for NVIDIA? also the description of how Fast-Sync works doesn't match what NVIDIA told during the presentation to the press and my own experience too. It actually doesn't work only when the framerate is at multiple of the screen refreshrate, it just conveniently choice to sync at such multiple when fps are close to that value (for smoothness reasons).
