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.

So, 2 separate but related questions:

1) For games that use the Vulkan renderer, like Doom Eternal, should we be using borderless fullscreen or exclusive fullscreen?

2) Not sure if you’d know the answer to this one, but since Proton on Linux uses a DirectX-to-Vulkan translation layer, should people use the recommendation for question 1 above, or say if a game is DirectX11 before taking into account the DX-to-Vulkan translation do use Fullscreen/Exclusive Fullscreen as if we were on Windows.

For reference, I’ve replicated the optimal G-Sync setup on my Linux machine, and since switching I’ve just been doing “If it’s originally DX11 or lower? Fullscreen/Exclusive Fullscreen. If it’s originally DX12? I use borderless fullscreen”

Sorry for posting so much but I have one last question, I just bought the acer Nitro XV275U F5BIIPPRX, it’s a free sync premium Pro monitor but isn’t g sync certified. It should still work with g sync no problem right? I have it turned on same usual settings, g sync indicator is working and on in the top right corner, but just want to make sure it’s fine? It seems like it is but I’m not the expert

With the newest drivers nvidia has now gotten rid of the nvidia control panel. Does this change anything for how to implement g sync? Has it changed any behavior to your knowledge? I keep g sync on, v sync on and use a frame rate limiter of RTSS. I also use v sync globally. I just had to use DDU due to sudden instability after installing the newest drivers and that’s when I found out nvcp was missing.

What’s the best way to go about using both technologies? My main game is CS2, where i use Fixed Refresh. I want to use G-SYNC in pretty much every other game though. It seems that in order to do this, i have to enable G-SYNC in the global settings, then set CS2 to Fixed Refresh in Program settings. I would rather do this the other way around though (though it doesn’t work) since I play CS2 most of the time, and the long alt-tab times are annoying (unless there is a way to fix them) due to the game not using G-SYNC, while the rest of the operating system operates with G-SYNC.

I have a new question. I have two monitors, both of which support G-SYNC. However, I only use one screen for full-screen gaming, while the other is used for watching videos and browsing the web in extended screen mode. I’d like to ask if both monitors need to have G-SYNC enabled simultaneously? Their refresh rates are also different. I only want the primary gaming screen to perform at its best, so will the setup for both monitors be relevant? Looking forward to your answer.
