On bad days and rounds, the upload bar is much higher and then also has jitter. The packets from the game server reach me demonstrably faster than my packets reach the game server.
There's a discrepancy between download and upload.
It's like watching a movie where the video and audio no longer match (are out of sync).

If it's not too much trouble, show the results

- No gamer is experiencing bufferbloat (or they're doing something really wrong)
That's why I asked for a speed limit. I don't care about buffer overflows.

I often do not clearly state my thoughts. google translate is far from perfect. And in addition to the translator, I myself am mistaken. Do not take me seriously.

I've already tested everything here.
- Upload ping manipulated
- Download ping manipulated
- Download and upload ping manipulated
- Receive packets manipulated
- Send packets manipulated
- Receive and send packets manipulated
- Download bandwidth manipulated
- Upload bandwidth manipulated
- Download and upload bandwidth manipulated
There are a few things that help, BUT IF THEY HELP, it works without them. Once the problem is there (upload jitter), NOTHING helps. No Windows option, no manipulation, no router, no VPN... simply nothing!
Why shouldn't the game crash if the download is so different from the upload?
The game shows, for example, 15 ms.
From game server to you = 5 ms
From you to game server = 10 ms
Of course, this can't work well.
Even if the download area were completely error-free (0ms jitter), you won't just experience upload effects like hitreg. The entire game will be thrown off track and everything will be messed up. Of course!

By the way, the CS2 documentation is wrong.

Hey LaggyTyp,
I am back.
Everyone, test this - uninstall all your chromium based browsers. Chrome, Brave, Mozilla, Opera.. Uninstall all of them, play your game, and let me know the feedback

.. Fingers crossed !!!
Trust me… Do this and tell me what you see..

Don’t know. Removed all that shits and can’t believe they were the reason. Have a check that any other browser is not installed ?

I have an Archer C6 router, sometimes I enable QoS and limit the download and upload to 120. It works well for a couple of matches, but then the desynchronization comes back.

None of my friends have such problems. These are gamers who even have pre-installed browsers on their pre-built PCs. Some even have multiple browsers installed.
No, no, no, that's not a solution.
For me, it's due to:
- Segment overload (especially upload)
- Jitter
- Hardware solution that bundles packets
A deadly poison.
