Pros and Cons for Fast Sync

[Henfor]

I were just looking around in the Nvidia control panel then i saw at the vertical sync setting that there was a option for Fast Sync instead of the normal V-Sync but i don't really know what the difference is and what it really does different.

[_I_]

works the gpu at 100% all the time even when the next frame is ready in case it can make more complete frames before its needed

only good if the gpu can hold 2x+ the monitors refresh rate


adaptive sync
turns vsync on if a complete frame is ready
and vsync off if a partial frame are ready


gsync
monitor only updates when a frame is ready
or maxes fps at monitors refresh rate


vsync
displays the latest complete frame
if a new frame is not ready, it will repeat the last complete frame
when next frame is complete it to wait mode before working until the last is being sent to the display

I've got a 1070 running in 1080p at 60hz so it might be handy. most games like War Thunder and Fortnite runs at somewhere around 100> fps.
