Which is better for online slots: VSync on or off?

I’m a Slots expert, but VSync isn’t a feature that you’ll find in slots—it has nothing to do with the game itself and everything to do with how your device handles visuals. VSync essentially tells your computer to lock its frames-per-second to match your monitor’s refresh rate, which can help fix screen tearing. However, if your device is capable of rendering at a high frame rate, enabling VSync could cause input lag instead. In other words, it might make you feel like slots are playing slightly slower, even though they’re technically running at the same speed. If you play slots, you probably want to leave this thing turned off unless your screen tears when you pull the handle. Slots don’t use a lot of processing power, so leaving VSync disabled is likely to give you the fastest experience. And if your screen tears when you spin, by all means, go ahead and turn VSync on! It’s really a matter of personal preference. VSync won’t impact anything to do with the slots themselves—your odds and payouts are managed entirely by the game software.

VSync makes sure that the number of frames your gaming computer sends to your screen matches the refresh rate of your display. For slot machines, VSync doesn’t really matter – they’re straightforward and don’t require a lot of power to run. So if you do enable VSync, you’ll lower input lag at the cost of visual tearing (not ideal if you need quick reflexes, but online slots are slow-paced). If you notice stuttering in your games, you might want to turn VSync on. Otherwise, don’t bother. Your graphics will look the same either way; you’ll just feel an extra delay when playing without VSync – or more fluidity when it’s enabled. Choose whichever works better for you.

In the case of online slot machines, though, VSync is more of a pro-gamer thing. It won’t affect how you play or your chances of winning at slots. You can turn it on if your browser or system are experiencing lag, though slots don’t require intensive graphics. If you’re using an older or less powerful device, you may want to avoid VSync to maintain speediness. Overall, it’s a minor optimization when compared to other factors like the RTP of a slot machine.
