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.

Hi I just recently bought the new Asus PG259QN 360hz Monitor just wanted to get a little bit of information on what’s best for a competitive settings/setup.

– Should I use g-sync with the optimal settings or Fixed refresh uncapped ?

– Game I usually play is siege and its uses DX11 & vulkan api, should I run DX11 api with LLM on/ultra or vulkan with LLM off ?

Also is it fine to use display scaling or GPU Scaling in nvcp does it matter in g-sync fixed refresh rate settings ?

– I also use 2 monitors one is at 60hz can go to 144hz and one is my main at 360hz will that conflict with anything including stutters etc?

Hi, I understand that gsync barely adds lag compare to only vsync and offer a tearless experience but how does it compare to the fixed refresh settings? which one gives the lowest input lag? (At frame rates lower than refresh rate and higher than it, each case to its own of course)
Thanks!

Nice bit of info here. Cheers! Is it possible to avoid screen flickering when fps drops below 30 when the gpu usage is low? Like forcing it to run at minimum 30 fps even if the application doesn’t want it to?

Hello, God of Knowledge.
G-SYNC ULTIMATE VS G-SYNC VS G-SYNC COMPATIBLE

Is G-SYNC ULTIMATE or G-SYNC more advantageous in Inputlag than G-Sync compatibility?

Can you say that the compatibility between G-Sync and G-Sync differs in the smoothness of the screen?
