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. When playing in Fullscreen or under Vulkan, as far as PresentMon/OCAT could tell only V-Sync of the in-game options actually introduced any latency. Of the driver-side options, it was again only the basic v-sync option to add latency, according to PresentMon/OCAT, with the Fast Sync, Enhanced Sync, and Frame Rate Target Control all appearing to send frames out just as quickly as they were available to send.
