With my Freesync 2 / GSync compatible monitor, I simply leave VSync off and cap at 144 (144hz monitor). I don't notice any tearing even at 144. I do notice tearing if I turn Freesync off. 144 is still within (at the top of) the range at which it works. Is it really necessary to enable VSync and/or Cap my FPS below 144?
I don't know how scanout sync works with Freesync 2 monitors, but if you're not noticing any tear or judder then I wouldn't change anything. Freesync 2 uses an FPGA or other type of hardware addin just like G-SYNC and G-SYNC Ultimate monitors do, as far as I know.

Don't you get tearing with pre-rendered in-game video though with vsync off?

I believe the suggestions to cap framerate below the monitor has to do with input lag measurements done by some folks. As you say, as long as adaptive sync is still functioning, you won't see tearing either way. But at least with gsync (not sure about freesync) there are benefits to ensuring you're not railed at the monitor refresh.

I personally do not notice the input lag difference, but I'm not a pro gamer by any stretch. YMMV.

Hello,

So the whole situation is, I’m having a screen tearing issue. As you can see from my specs I have a decent rig, I’ve been having screen tearing issues ever since I reset my pc. I never used to have screen tearing issues and I know exactly how gsync works. Right now if I cap my FPS to 144 (my monitors refresh rate) I get even worse/ noticeable screen tearing. Like I said. I never used to have this issue, even with uncapped I didn’t get screen tearing. Now I just do. It’s so annoying I’ve been trying to figure it out the past week and I’m so tired of it. What bothers me is that knowing my pc used to be fine and now I’m having this issue. And please don’t tell me to cap my FPS to 138 or play with vsync or even tell me how gsync works because believe me guys, I already know. What kind of fixes the issue is putting vsync on in global settings but I never used to need to do that, right now that’s what I’ve done and for most of the games I’ve tested to see if I have screen tearing , I don’t apart from one game League of Legends. I just want to know or get advice on what could’ve possibly gone wrong or maybe I might be missing certain drivers or something like that, I am not a pc expert and I really need help troubleshooting this issue. What can i do to fix this. Sorry if I sound quite rude but I’m just tired and I want to find a solution to this. Is there a setting I should have on or something, I just need help guys as this is very frustrating. Again sorry if I sound rude.

Also I had a 1080 and recently upgraded to a 1080 ti, I was having this issue with my 1080 as well. (After I reset my pc)

also i should add im on windows 10 pro 1909

You obviously don't know what you're doing otherwise you would know you want to cap at 2-3fps below refresh and turn gsync+vsync ON in the CP. You may be having trouble with a new driver. Also that is a freesync monitor not gsync.

I tried the built in frame limiter in the driver, but it doesn't work well. I set it to 73 and 74 (75hz monitor) and in both cases I got terrible stuttering, while with vsync on and no limit the frame rate is smooth
It's not terrible on my end, but I do notice some random small stutters when I have the limiter on (141fps in my case for a 144hz monitor), regardless of the frame rate.

Do I need to enable V-SYNC in games for G-SYNC to actually work or what?
Because right now I have G-SYNC enabled in the nvidia control panel for full screen apps but still clearly see tearing in games.
Unless I enable the v-sync option in the game. Yes, the game is set to run exclusive fullscreen, not borderless or windowed mode.
This sounds like gsync is not working. Which monitor? Are you definitely plugged into the gsync display port? some monitors also have non gsync ports like hdmi for convenience.
Any settings on your monitor to enable or disable it? My monitor has a light that turns amber when gsync is active. If I enable backlight strobing it disables gsync.
