Does Vsync help?
Hmm, after going through that, I think it’s not as severe as you suggest* but still quite problematic. You’re correct it’s pretty bad and I’m struggling to pinpoint exactly what’s causing it. Spoiler * The performance figures for v-sync match the ideal baseline—around 14 to 27 ms—which means it won’t improve beyond that. So any other numbers should be measured against something slower, not just their own delay time. The vsync results in similar conditions range from 89 to 108 ms, which you pointed out is extremely high. But remember, we’re comparing to the same starting point, so the real gap is actually 62 to 94 ms worse than with it off. Moreover, based on this analysis: it’s likely the pre-rendered frames I mentioned might be involved, possibly reducing the delay to about 33 ms or more. That would mean vsync could drop to around 29 to 61 ms—or even as low as 12 to 44 ms in an ideal scenario. Still, given all the adjustments made to eliminate possible delays, it’s clear this isn’t negligible.
Ultimately you need to choose your settings. If your display can handle the frame rate or higher, it will improve smoothness and eliminate jitter, though failing to match may cause more stutter. It also introduces a slight delay, as noted. Your decision is yours.
The buffer for VSync is set to one frame or a custom number, but it creates noticeable lag because it delays output rather than simply waiting before sending frames. This introduces significant overhead. The idea of a "huge delay" depends heavily on the game and can vary widely. For me, a substantial delay means it impacts gameplay noticeably, and VSync often causes that. Some games become unplayable with VSync due to this lag, while others work fine or are barely affected. Even GSync isn't a perfect one-frame solution, as indicated in the article you referenced. I only reviewed it briefly, so I'm unsure if they accounted for baseline input delays. If they didn’t, GSync might have been closer to that threshold.
The issue arises because the monitor needs to align with the GPU, forcing the GPU to perform significant adjustments to stay in sync, which leads to delays.
you're someone who excels in fast-paced FPS games (with top skill), you'd definitely prefer a delay-free experience over VSync, believe me.
the vsync lag appears less obvious on controllers because of dead zones, but on a mouse it’s much more apparent. increasing sensitivity makes the aim more affected by this delay.
That's a strong statement—no way a 100ms delay can ruin your performance.
