What are the pros and cons of turning VSync on/off in casino games?

VSync makes casino games (slots, video poker) run more smoothly, as it matches the game’s frame rate with your monitor’s refresh rate. That means less screen flicker (the effect you see when images become misaligned). Unfortunately, VSync also adds more lag to your inputs; you’ll notice a fraction of a second from when you click/tap on something until the game responds. If you're playing live dealers or tournaments, this could be problematic. Disable VSync if you want less input lag. You'll have higher responsiveness, but some screen tearing. If you're doing a lot of side bets, it wouldn't hurt to disable it. If you're a casual player, having VSync on is probably okay for you.

VSync minimizes screen tearing by matching your video game’s frame rate to that of your display. This leads to more fluid animation – excellent for playing classic casino games like slots or roulette. But it also introduces latency. That can be a problem in live games or fast-paced minigames. If your PC can handle it, I’d recommend having VSync enabled (though you’ll probably want to disable it during live dealer games). In general, it just boils down to whether smooth visuals or low-latency input is more important to you in any given game.

Enabling VSync will reduce screen tearing issues by matching the game’s update rate to that of your monitor. However, this can introduce input lag that can be frustrating in dynamic casino games such as live blackjack or slot machines with high-spin speeds. If you prioritize performance, disable VSync. Switch it on if you’re willing to tolerate some input lag in exchange for reduced visual lag.

While VSync reduces screen tearing by limiting the frame rate, thereby resulting in a smoother-looking display, its use can introduce an additional layer of input latency, which is likely undesirable in a game that requires precise timing of button presses or quick swiping actions. If you have a powerful PC with little trouble rendering at high frame rates, consider enabling VSync; otherwise, especially if you have a weak internet connection, it might be better left disabled.

With VSync enabled, your GPU will limit the frame rate of your graphics card to match your display's refresh rate, thus avoiding screen tearing. The primary advantage here is that your visuals will be more fluid. But, enabling VSync also adds some input lag, which can be a problem for highly competitive casino video games. So enable VSync if you're playing slot machines or slower-paced games; disable it when playing live dealers. It all depends on your personal sensitivity to input lag.
