Is 144hz G-SYNC Necessary?

[Ty_Cox]

If I am running a 144hz monitor without G-SYNC, and my GPU can consistently produce 144 fps (1080p), will there be screen tearing?

 

My friend wants to buy a less expensive monitor, the one attached, and he has a RTX 2080 Super.

No, tearing occurs when frame rate and screen refresh is out of sync.

G Sync fixes that problem.

YES

 

Screen tearing will happen unless u have some kind of sync active, be it Vysnc, Fast Sync, G-Sync, or FreeSync.

 

Even at 144fps on a 144hz monitor, without sync enabled, the frames exiting ur GPU wont always be synchronized with the Display, frame times fluctuate, so without some kind of sync u WILL get screen tearing, whether u notice it or not is down to you.

 

At 144hz, unless every single frames frame time is 6.944ms, ull end up with tearing.

So for example if u get:

6.89ms, 6.90ms, 6.87ms, 6.94ms, 6.89ms, 6.99ms,7.00ms,6.94ms.

Thats not consistent and ull get tearing, but will show up as 144fps,

 

Vsync and fast sync ensures those frame times are the same,

Adaptive sync ensure the monitor refreshes at the speed the frames time are at. Both result in no tearing, but without it u get tearing.

You'll notice tearing more the further out the frame times are from the target refresh frequency.
