G-SYNC 101: Hidden Benefits of High Refresh Rate G-SYNC


Bonus Points

Often overlooked is G-SYNC’s ability to adjust the refresh rate to lower fixed framerates. This can be particularly useful for games hard-locked to 60 FPS, and has potential in emulators to replicate unique signals such as the 60.1Hz of NES games, which would otherwise be impossible to reproduce. And due to the scanout speed increase at 100Hz+ refresh rates, an input lag reduction can be had as well…

Blur Buster's G-SYNC 101: Input Lag & Optimal Settings

The results show a considerable input lag reduction on a 144Hz G-SYNC display @60 FPS vs. a 60Hz G-SYNC display @58 FPS with first on-screen reactions measured (middle screen would show about half this reduction). And while each frame is still rendered in 16.6ms, and delivered in intervals of 60 per second on the higher refresh rate display, they are scanned in at a much faster 6.9ms per.

Why do you think that basically no (to my understanding) cs:go pros use these settings or anything similar? Just regular settings with no capped FPS. Is it lack of knowledge or what do you think?

Hey jorimt,

Just a quick question after reading your guide on G-sync + V-sync and input lag…

So I understand that if G-sync is used in combination with V-sync, it would essentially be forcing the computer to deliver steady frame timing over the period over a second (so for 144 Hz they would all be 6.9 ms versus the 144 frames averaging out to 6.9 ms). Also from what I understand, all of this discussion is related to changing these settings withing the NVIDIA control panel.

What does this mean with regards to in-game settings say for a game like Apex Legends or Modern Warfare? Do we have ENABLE V-sync within the individual games as well, to see the benefits from the G-sync + V-sync settings in the Control Panel? Or is doing so not necessary, and might cause other issues?

Hello, jorimt.

This guide just rocks. I have just one question about the new Nvidia driver setting “Max Frame Rate”. From now on, I can set the maximum frame rate that the GPU will render a game directily in the driver.

Is there a difference in latency between set the max FPS at the driver new option or in the RTSS?

Thank you!

Could you explain this line a bit more? In a 240 Hz 60 FPS CAP example, for instance?
