Perfect HITREG and NO Desync while VSYNC ON , but...

[gipzy666]

I’ve been dealing with input lag and desync issues for years, and I strongly believe the main cause might be the lack of proper grounding in my home. I mainly play Valorant, and here’s what I’ve noticed:

When I enable VSync and uncap my FPS (on a 144Hz monitor), I get perfect hit registration and no desync at all. But when I turn off VSync, enemies start jittering or teleporting, and it feels like they can see me before I see them — as if my game is out of sync with theirs. This seems more like a frame synchronization problem rather than a pure network issue.

On top of that, I can’t spray properly with weapons like the Vandal or Phantom, because it feels like the recoil is lagging behind my movements — it’s just completely off. Interestingly, there was one time when I tweaked my transfer and receive buffer settings, and it actually gave me perfect hit registration and smooth, accurate sprays.

Of course, I can’t play with VSync on permanently because it introduces heavy input lag, and I’ve already tried Fast VSync, Ultra Low Latency Mode, and other similar settings — but none of them fix the issue. I still end up with desync and Ferrari-peeking enemies.

So what’s really going on here, and is there anything that i can possibly try to somewhat make it better?

Did you enable Vsync in-game or in NVCP?

In addition, I suggest that you change the low latency option in the game to on or off,
Ultra-high cause me to be out of sync.

Had similar experience and Vsync ON in Val.

Randomly decided to turn ON and play with 60Fps and immediately start notice how my game changed while in match and from round to round better and my hitreg start somehow to connect better and so on and everything what you describe too...like i had more time and finally able to hold angles without get insta headshoted...


And I was like lucky in that moment and would even accept play with Vsync ON always but just in the next Match and the more I played...it only become worse and same like with uncapped and without Vsync ON...


So you sure that you dont have just same ? and like it only worked for only short moment and make some small noticeable change ? How long and how many matches you played and you tested with Vsync ON ?


But I believe you...cause I know exactly what you talk about and the feel of this improvements and suddenly change to better.



Here one interesting thing that you should try too...Cap your FPS Ingame just to 30 and play some Match like that and in Halftime or some later just uncap...tell what you feel after and what going on and happens...


But here one more thing and which you should dont ignore...there exist Console Players and who already capped to 60fps or 120fps by Hardware/Software but are experience same Story like we do all and can tell differences and same feelings and changes and with Online Gaming...which i think is interesting too or not ? You should think about this too...

enable adaptive gsync + vsync + ull nvcpl in same time.

From what I've researched, enabling vertical sync stabilizes the PC's power consumption, creating better synchronization with your electrical grid and significantly alleviating problems. However, unlocking the FPS creates random power consumption that the grid can't handle properly.

I don't have a clear solution either and am not sure there's any 1 particular solution, particularly on PC. There's usually dozens of different things to try, there's like a thousand switches available that may be causing bugs. I can't say the experience seemed much better on console.

Try adaptive sync/vsync off, frame cap off, in borderless window mode, that works for me sometimes. Sometimes fooling around with the vsync settings, off in game, on in gpu cp, may work. It doesn't seem to add that much input lag but may cause desync. I have a freesync/ gsync campatible monitor, I think it's buggy. The Samsung G4 1080p 240hz. I just used the DSR at 4x and put it in 4k 240hz, looks great. I turned off async/vsync, windows in 4k, game in borderless 4k.

Then the tick rate in the games, I don't mind playing at lower fps but it's like the only thing to do on PC at least is unbuckle the frame rate and get as many frames as you can, at least 120fps seems to be the minimum. Even when the tick rate/ server side frequency is 60hz it's like at 60fps I still feel handicapped and like I'm going slower than the other players, just insta killing me. Could be a delusion but I am uncertain but I definitely feel handicap. I can play in lower frequencies with triple buffering on, it looks fine to me but the input lag then handicaps you. It's supposed to be dedicated servers, which would be optimal. But I think it's Client Host P2P, or just P2P and the I.T. guys are full of bologna. Because it sure feels like P2P anymore, which was formerly horrible over the last decade. It's not that awful these days but everyone is handicap to the Host. I don't know how it works entirely; I'm not a network engineer.

As far as networking we're told to just leave the PC defaulted and not to meddle with anything. But that whole "Recieve Side Scaling" bushwa was a laugh. If you have RSS on, you want to set que's to 2 instead of 4, usually. Then have Offloads on. If RSS is off, you want Offloads off. - I couldn't find clear documentation on all that, even MS documentation was vague.

Then the driver issues with the Realtek, idk if the newer drivers fixed the RSS issue, I just turned RSS and offloads off.

I had the Intel NIC and it seemed excellent out of the box.

Then it says leave QoS on, or Qos may cause lag. Idk...

Do not use a custom DNS.

Firewall may cause lag... But turn it off only if your PC doesn't have sensitive documentation.

I love online deathmatch, battle royal, but the overall sense of automation, AI, bots, has really been ruining it for me. There were people grouping in solo's cyber bullying me in multiple games, then crazy crack shot snipers everywhere. Really weird crazy shots I do not think were humans, namean.

Mouse, I'm using the Asus ROG Gladius modular switches, with silent switches, it's great. Defaults at 800dpi. I did not install Asus armor crate, it was crazy bulky, laggy, and a lot of it was still in Chinese which I can't read, unfortunately. Sometimes the mouse or software may be an issue I've read, trying to switch the polling rate to a lower frequency. Most modern games should be fine, I think.

Then just finding a private server/games or group of regulars to play with is best but no progression.

¯\_(ツ)_/¯

enable adaptive gsync + vsync + ull nvcpl in same time.

LLM in nvcp will cause Desync
，It's best to set it to off.

with gsync+vsync - no

More likely with -reflex on, it should override LLM (even if it somehow messes up with it so thats maybe the source of the LLM desync urban legend...)
