Desync / Input Lag / Output lag - Journey to Eliminate Latency

Everything about latency. This section is mainly user/consumer discussion. (Peer-reviewed scientific discussion should go in Laboratory section). Tips, mouse lag, display lag, game engine lag, network lag, whole input lag chain, VSYNC OFF vs VSYNC ON, and more! Input Lag Articles on Blur Busters.

Like many here. I have tried everything possible so far that I can do to fix this desync/input lag. I travel with a good gaming laptop.

And would like to add that THIS PROBLEM EXISTS EVERYWHERE. I have tried in many different countries such as US(home country), UK, Netherlands, Indonesia, Japan etc. that have all electrical and internet connection. It has been same issues and they come about same way.

So only theory left is that either the gaming laptop/peripherals are corrupted forever after connecting it in my home country first or that it is something related to the body theory. Idk how to make sense of all this logically. And yes I already tried many different configuration of PCs and laptops already. All had same issues. Only thing I haven't tried yet is buying completely new setup of everything at a new location.
Hello. Please don't consider this trolling. I'm from Russla, and I happen to understand roughly what you're talking about. I would like to clarify the case when you made different installations and traveled to different locations around the world and you still have a problem. Have you tried many things and even more, but have you tried activating your Windows with an official Microsoft key?. I say this from the position that I have always been using licensed Microsoft software since 2015, and none of my installations have experienced such problems. On the contrary, my friend used a pirated Windows key on his PC, I built the computer for him myself in 2023, after activating the kms server and then rebooting the pc, a cloudy picture appeared and the system did not work as responsively as without activation. To solve this problem, we changed the motherboard and bought a key, unfortunately it is very expensive, but it was worth it. I'm saying this because you've tried the most unconventional methods, but what about the obvious ones?
Once again, this is not trolling, I'm not saying that it will help you specifically. Just sharing my experience. I've never encountered this myself, only on a friend's PC, so I can't imagine how hard it was for you to go all this way, I'm really sorry :(

Laptops I tried came with original windows keys and they get activated automatically for me. Is that not the same thing?

In this case, it's not Windows, unless you're absolutely sure that the laptop was supplied with the original Windows, and not the cmd kms activator. In any case, I wish you success, I really hope that you will cope on this difficult path!

Hello, I have the same problem as you where I am late to fight and get out gunned.

Only play 1080p
fotnite performance all low
fps unlimited

Here are my computers:

Computer 1

280hz monitor acer display port single monitor
CPU 5900x
Ausu Tuf X570 Board
DDR4 32 gig ram
RTX 4070 memory 6x 12gig on OG card
Current Nvidia Driver only

850 watt psu Corsair
windows 11 latest version fresh only video driver and fortnite.
feel lag in fortnite get out gunned everytime late to party sort of

====================================================================================================================

Computer 2

280hz monitor acer display port single monitor
13700k with only p-cores 8 + 8 e-cores
Msi Edge board
DDR4 32 gig ram
also used same card swapped in RTX 4070 memory 6x 12gig on OG card had god fps and frametime but delayed.
Current Nvidia Driver only

feel lag in fortnite get out gunned everytime late to party sort of

also have 6700xt 12gig used in both systems testing fortnite. No lag and I can kill enemies in game or at least have a 50-50 chances
with Driver 22.11.1.0 WHQL
get like 280-390 fps in performance mode on reloaded fortnite plays very smooth and good frametimes.



even tried a rx9070XT but returned because get more constant fps with 6700xt I know crazy but 9070xt is a beast but not for 1080p like I play also no delay like RTX4070.

I think RTX 4070 has Issues of not showing screen fast enough maybe 150ms - 200ms delayed some how not sure how ???

I also have to test more on this.
1080ti
970 GTX
A2000 RTX
R580 AMD

I recently tested a power filter (PF-400USB - TAGA Harmony) that cleans dirty current. The power filter is used by audiophiles to eliminate interferences. Unfortunately it did not help, the problem still persists.

I made a short video to show, how the problem looks like for me.

phpBB [video]


I have right peak advantage and I bait the enemy, I know he will run on me and I am ready but I see everything later.
I have reaction time like a professional rally driver 120-130ms in humanbenchmark,
very good hardware 480 hz / 480 fps / 29ms ping
and in game there is delay like hell, everyone sees me faster and shoots faster.
