@All
Anyone explain framerate and Refresh Rate connection? Like which FPS suits better on wish Refresh Rates?
Ex- will 60 FPS feel different on 120hz screen vs a 144hz screen?
Also I still don't know that's the use of VRR
It can be complicated, but the best rule for refresh rate and FPS without VRR is that FPS matches refresh rate, or can be multiplied into the refresh rate.
So if you have a 60hz TV, the best framerates are usually 30 (x2) or 60 (x1). 20 (x3) can be neatly multiplied into 60, but in all practicalities it’s too low.
For 120hz displays, the same rule applies if it’s a fixed refresh rate. 120fps (x1), 60fps (x2), 40fps (x3) and 30fps (x4).
If your framerate doesn’t match your refresh rate, you’ll get screen tearing. V-sync fixes this, but can introduce input lag and can cap your game’s framerate much lower than it’s in theory capable of.
What VRR does is it changes the refresh rate of the display in time with the framerate of the game, thus eliminating screen tearing without any of the downfalls of v-sync.
So if your game is playing at 70fps, the display will refresh at 70hz. If your framerate changes to 73fps a few seconds later, your refresh rate will adjust to match.
VRR has a limited range depending on the display, so it can’t necessarily do 1-144hz, for example. But some displays can also do the multiples thing assuming a refresh rate it can do is a multiple of the framerate.
So if your TV’s VRR range is 48hz - 120hz (a common VRR range), but your game is running at 30-35 fps, it can in theory multiply those framerates by 2 and display it in a higher refresh rate. So if your game is playing at 31fps it could change the display’s refresh rate to 62fps so the frames multiply evenly into the refresh.
VRR has its own issues related to the quality of the display, however. A cheaper panel may display different refresh rates at slightly different brightness levels. This means if your framerate varies a lot at the brightness thresholds you get VRR flickering.
And of course some games just don’t work well with VRR for whatever reason, as was my case with The Talos Principle 2.
To better answer your question, I don’t know what 60hz looks like on a 144hz display as I’ve never had one of those, but I can’t imagine it’s good. I suspect 72fps would look better as it can more evenly multiply into the refresh rate. But the 144hz display may be able to switch into 60hz or 120hz modes depending on the panel, similar to how OG Steam Deck can display at 40hz despite being a 60hz max panel.
