Gsync fps cap

[AkSo2504]

So i have read a few times now that the best setting for a gsync monitor is to set a fps cap at 3 fps lower than your refresh rate(for me 162 because i have 165hz) so it stays in gsync range. But for example cs go feels way smoother and more responsible with 300fps+ and i am not noticing any screen tearing. So would it still matter to be in gsync range even if i dont notice tearing?

You're mixing GSync and FreeSync. GSync caps FPS by itself in hardware, FreeSync doesn't, you need to enable VSync (and get some increase in input lag) or cap the FPS by other means.

Gsync doent cap the fps im pretty sure

It does.

Look it up

Gsync is just changing the refresh rate of the monitor in its range so it matches the fps not the other way around

Upon its release, G-SYNC’s ability to fall back on fixed refresh rate V-SYNC behavior when exceeding the maximum refresh rate of the display was built-in and non-optional. A 2015 driver update later exposed the option.

This update led to recurring confusion, creating a misconception that G-SYNC and V-SYNC are entirely separate options. However, with G-SYNC enabled, the “Vertical sync” option in the control panel no longer acts as V-SYNC, and actually dictates whether, one, the G-SYNC module compensates for frametime variances output by the system (which prevents tearing at all times. G-SYNC + V-SYNC “Off” disables this behavior; see G-SYNC 101: Range), and two, whether G-SYNC falls back on fixed refresh rate V-SYNC behavior; if V-SYNC is “On,” G-SYNC will revert to V-SYNC behavior above its range, if V-SYNC is “Off,” G-SYNC will disable above its range, and tearing will begin display wide.

My bad, it doesn't do that by default now, but if you enable VSync it's actually not software VSync but GSync's hardware one.

Back to your question, it is indeed better to limit FPS manually 2-3 FPS down from display refresh rate to reduce latency.

Its kinda weird because my friends say that it feels smoother and more responsive when uncapped and also most cs go pros have it uncapped because of the same reason, so im very confused

Wow, that answers a question I've had for years. I used to have a 1080 (I think I had a 970 at the time which I later swapped for a 1080) and a G Sync display and I never had to enable V Sync, it would do it automatically. Then one day it stopped working and I had to enable it manually. I asked why here and was told that it never worked that way despite it working that way for months. I guess they changed it in a driver update.

 

At least now I know.

It might feel smoother because with native 144Hz refresh rate the interval between frames are exact same and consistent but if you say cap it to 142 FPS then 2 frames out of 144 have rendering interval twice longer than usual, i don't think you can feel that tho but there may be some other factors contributing to apparent latency. Just use what setting feels smoother for you.

Well if you set it to 142 your monitor will run at 142hz because of gsync.

Yeah, you're right, then there shouldn't be any additional latency or difference in smoothness. Might be just placebo effect then.
