What is the Difference between Nvidia G-sync Vs V-sync?

G sync

It mainly allows for a dynamic refresh rate that matches the output from your graphic card. It means suppose your graphic card can produce max 130 fps(frames per second) for a particular game, so the Gsync will synchronize these fps to the refresh rate of your monitor. Mostly Gsync is effective when you go below 60fps,you screen will not stutter. So let me tell you what G sync technically do, It updates the screen exactly when the frame is finished and ready to be up by the graphics card whether that is 55 or 59fps. It removes all the problem associated with vsync matches fps, no lag and no stutter. It gives Incredibly smooth, tear-free gameplay at refresh rates up to 240 Hz. NVIDIA built a special collision avoidance feature to avoid the eventuality of a new frame being ready while a duplicate is being drawn on screen (something that could generate lag and/or stutter) in which case the module anticipates the refresh and waits for the next frame to be completed.Overdriving pixels also becomes tricky in a non-fixed refresh scenario and solutions predicting when the next refresh is going to happen and accordingly adjusting the overdrive value must be implemented and tuned for each panel in order to avoid ghosting. Unique features like HDR, frequency-dependent overdrive, and ultra-low motion blur, And a powerful competitive advantage that has made G sync displays go-to equipment for enthusiast E sport players.

V Sync

So before G sync existed we had two modes V sync off and V sync on. So when we turns it off we gets what's called tearing that is basically saying graphics on your screen might contain part of the last frame and part of current frame. And in worst cases you can get multiple tears across the screen so you're seeing 3 or more separate frames on your screen with objects in different positions.With vsync on you will not see any tearing, but , in order to compensate the screen will simply draw two of the same frames whenever your frame rate dips below your refresh rate of the monitor. So basically V sync on means you have 60 hz display and you will run exactly at 60 fps unless your graphic cards (for ex) dips to 59fps just even once , it will draw 2 frames just for that one frame and that is stutter. The other problem with V sync is the lag (which causes input lag). But G sync solves this problem, i have already told you about G sync.

CONCLUSION

So my ending thoughts are, unless you are a ultra pro gamer, Above 60fps you will not notice any big difference with G sync on or off. G sync only helps when your fps go below 60. You screen will not stutter below 60fps with G sync on, with off it will stutter like hell. So if you have budget totally go for G sync screens otherwise not.
