Also, if the performance cannot reach 60FPS due to a particular in-game scene being too detailed, the graphics cards will be forced to run at a lowered 30FPS until the game reaches a point with less demanding picture quality. However, this limits the performance of high-end graphics cards. In simple terms, V-sync is a function that prompts the graphics cards to output 60FPS videos at 60Hz frequency, so as to avoid screen tearing issues. In the past, in order to provide a smooth picture when playing video games, we would turn on V-Sync (vertical synchronization).
The result is monitor refresh rates that aren't on par with the improved performance of the graphics cards, leading to more screen misalignment and tearing issues. Meanwhile, refresh rates for most monitors remain fixed at 60Hz. Considering that performance of graphics cards nowadays keeps getting better and better, the frames per second has become higher-even under high resolution settings. So when the monitor refresh rate is not in sync with the graphics card's frames per second output, there will be tearing or lagging of the game screen, impacting the gaming experience. Why do game screens lag or tear? It's because while the refresh rate for computer monitors is fixed at 60Hz for typical models (which means the screen is updated 60 times per second), the frames per second (FPS), as presented by the graphics card when running video games, is not constant-it fluctuates up and down.
When the Display's Refresh Rate is Not In Sync With the Graphics Card Now, the two major graphics card manufacturers have launched their respective synchronization technologies-NVIDIA G-Sync and AMD FreeSync- to make games run much smoother in terms of graphics. In the past, V-Sync (vertical sync) technology has been able to resolve game screen lagging issues, but when it comes to results, there is still room for improvement.
A subtle lagging or tearing can render the game unplayable to gamers. When playing video games, in addition to realistic and refined game graphics, a smoother frame rate is an important factor impacting the thrill level of your gaming experience.
