Does Vsync help?
It improves fluidity while requiring significant processing time; removes screen distortion, though it introduces a substantial delay in input response.
VSync may cause a slight delay in input response because of its mechanics. Some users accept this trade-off for a more fluid gameplay. If the effect is unnoticeable and doesn’t affect your performance, keep it enabled. However, if you experience missed shots or unresponsiveness, disable it. Don’t rely on others’ advice—test both with and without it to see what suits you best.
It should be no more than one frame, and though people react differently, I’m uncertain that’s a significant delay
It's significantly longer than one frame. If you're unsure, review the blurbusters and various other reliable tests—VSYNC isn't one frame, but Freesync and GSync are different.
Sure, here are some links to the tests you asked about. Let me know if you need more details!
gsync at 60Hz typically shows 89 to 108ms input lag, while 240Hz delivers 28-33ms lag. The difference varies by game and is generally at least 70ms compared to vsync. However, vsync on 60Hz can still cause noticeable lag, though less than gsync. If you're keen on minimal delay, gsync may not be worth trying unless you're comfortable with the trade-offs.
I usually disable Vsync until I notice screen tearing. The extra delay from in-game Vsync is clear from my experience. It’s not a universal issue—people adapt over time and adjust accordingly—but it can be a real problem in competitive titles like PUBG. EDIT: You might try Nvidia’s built-in Vsync option or AMD’s version, though it hasn’t helped me so far; I still see tearing when it’s enabled.
