i cant adjust the height on this monitor what is a must have for me. so to be clear. a 144HZ freesync monitor will work like a regular 144HZ monitor. using vsync will prevent my screen from tearing and stuttering. the AOC G2460pf is height adjusteble and its'll perform like a regular 144hz monitor when using a Nvidia card. using this monitor will be fine for competetive CS:GO, thanks for your replys guys!
I actually disagree with the person saying this is correct. Vsync will eliminate tearing but it will not eliminate stuttering. That is exactly why G-Sync and FreeSync are popular.
Vsync locks your FPS to a multiple of your monitor's refresh rate. That means that if you aren't capable of holding 144 FPS the game will drop down to 72 FPS. On a normal 60 Hz monitor it will lock to 30 FPS.
The stutter happens when a game is right on the edge of those Vsync numbers. If a game is constantly switching between 144 and 72 FPS (or 60 and 30 FPS) on a standard monitor it will be very noticeable. G-Sync and FreeSync solve this problem by eliminating tearing by changing the monitor's refresh rate on the fly instead of trying to limit to the GPU to multiples of the refresh rate.
Edit: Since you are using the monitor for competitive CS:GO you probably won't have this stuttering problem since a 1070 will have no trouble maintaining a constant 144 FPS in that game. Most competitive players would not use Vsync though since it introduces input lag. FreeSync and G-Sync also wouldn't help anything at framerates above 144.
