Hello Everyone,
So I have recently come across an issue with CS2, regarding packet loss. My game runs super fine without issue, but when i try to stream the game using OBS Studio, i get a constant packet loss of 1-2% and same for packet miss, with a jitter of 20 ish (quite new so limited testing), when spiking i can get up to 20% packet loss, which happens somewhere between every 10-15 seconds. The issue is in-game, nothing is wrong with the stream and I don't seem to have any issue with other games. The issue is not new (Didn't come with the newest update), it was an issue even before the armory update. The issue with the streaming only seems to be network related, since if i put on delay the issue only starts when the stream connects to the server. I have also looked at the performance tab and resource manager while testing the issue and can’t find any problems indicating my pc should be the issue. While having the issue I also tried a ping test both to google server and DNS with no issues.
I have been using an entire weekend together with my ISP, where we tried many different things to no avail. They have concluded that the issue doesn't seem to be on their end or anything they can help with.
I’m gonna try to list some of the things i have already tried, i can’t remember them all but hope it helps to sort it out:
List of different specs that might be useful:
The only thing that seems to have been close to making any change is OBS’s “Enable network optimisations” and “Enable TCP pacing”, but when enabling these i get unstable streams with very fluctuating bitrate and really high in-game ping.
I have also linked to steam's own explanation of the telemetry of the CS screenshots, to those unfamiliar:

I have tried my best creating this post and writing the best english i could, in advance i wanna say thank you for spending time reading and trying to help.

I’m gonna try to list some of the things i have already tried, i can’t remember them all but hope it helps to sort it out:
- Turning off Nvidia Low Latency and Nvidia reflex
- All three “Smooth over packet” options
- Turning down “rate” command
- Updated drivers
- Turned off Nvidia shadow play and overlay
- Changed DNS server
- Restarting router
- Turned on DHCP
- Reinstalled OBS
- Selecting specific OBS server and automatic mode
- Changed bit rate between 2500-8000 (as well as audio bitrate)
- Turned down resolution and fps
List of different specs that might be useful:
- Windows 10
- 1000/1000 internet speed
- AMD Ryzen 7 5800x 8-core
- 32gb ram 3600 MHz
- Nvidia GeForce RTX 3070 Ti
- Samsung SSD 980 PRO 1TB
- Disable fullscreen optimisations ON
- Run as administrator for CS and OBS
- Attached cs config
The only thing that seems to have been close to making any change is OBS’s “Enable network optimisations” and “Enable TCP pacing”, but when enabling these i get unstable streams with very fluctuating bitrate and really high in-game ping.
