Hello,

Would you please recommend the lowest latency setting for my pc in COD Cold War? I have the 360Hz Asus monitor and get between 280-310 fps during game play. I currently have the monitor set at 240Hz with unlimited fps, V-Sync and G-Sync off and it is very smooth. Would it be better to change the refresh rate to 300 or 360Hz even though the fps most likely average around 280? Does it make sense to turn G-Sync on?

Your help is highly appreciated!

Thank you,
Vasko

Hello, I have a weird question.

Does G-SYNC still work if you lower the refresh rate (to something inside G-SYNC range) and use V-SYNC on in order to lock the FPS? Instead of running max refresh rate + V-SYNC on + -3 FPS lock.

For example: set refresh rate from 144hz to 120hz and activate V-SYNC so the game runs at 120 FPS and hz. In this case, will G-SYNC still be active? Or do you still have to set a FPS limiter to 117 FPS?

Will these settings have G-SYNC working as intended or will there be detriments to running games like this (except for running it at 120hz and 120 FPS, instead of 144hz and 141 FPS). If it works, does locking the FPS this way have any benefit over other ways of locking the FPS, and does it introduce normal V-SYNC latency if it hits 120 FPS?

Hi there, is there an optimizing guide for Free-sync?

what if a game only let you cap at a fixed refresh rate or unlimited rather than a custom value

So what actually causes the tearing from “Upper & Lower Frametime Variances”? Is it because G-Sync is somehow unable to respond to a quick change in frametime (I read somewhere it uses a fixed polling frequency to update the current refresh rate)? And in the Valorant clips with the FPS capped to 142, shouldn’t this result in a constant frametime or is there some problem with how the FPS limiter works (introducing inconsistent frametimes)? I also can’t for the life of me see any tearing in the second Valorant clip.

Thanks a lot for this article, it was a super interesting and informative read.
