Як працює VSync?

Is it better to have VSync on or off?
Turning V-Sync on will improve game quality in most games. But some minor bugs may occur when V-Sync is on. Turn it off if you experience some lag or distortion in the game.
Is VSync good for 144Hz?
Even playing at ~90 fps, you are better off NOT using vsync. Screen tearing or whatever else isnt really a thing when you have a 144 Hz display, so you never really need to worry about anything like that. So, leave Vsync off, and adjust your graphics settings to allow as high of a framerate as you can…
Why is VSync 60 fps?
New frame is rendered but old is still being read so vsync makes it so it waits for old one to be read and only then writes the new one to the frame buffer. This delay is what causes the input lag that vsync has. And due to it waiting for the read it means fps gets capped at 60.
Is VSync bad for GPU?
Yes, enabling VSYNC can reduce your computer's performance by limiting its frame rate. This can be especially noticeable in graphically intensive applications like games. However, some modern graphics cards and monitors have adaptive sync technologies like G-Sync and FreeSync that can mitigate these issues.
VSYNC synchronizes the frame rate of your graphics card with the refresh rate of your monitor, while framerate limiting simply caps the maximum number of frames …
VSync (Vertical Synchronization) – це базова технологія, що синхронізує частоту оновлення монітора з вихідною частотою кадрів від відеокарти.
