VALORANT causes my OBS YouTube stream bitrate to drop from 4000+ Kbps to 160–500 Kbps

Hey everyone,


I'm having a very strange issue with VALORANT + OBS Studio and I'm wondering if anyone else has experienced this.


I stream VALORANT to YouTube using OBS. My internet connection seems fine, and when VALORANT is closed, OBS uploads normally at 4,000+ Kbps.


But as soon as I open VALORANT, my OBS streaming bitrate suddenly drops massively:


  • VALORANT closed → 4,000+ Kbps
  • VALORANT opened → 160–500 Kbps
  • VALORANT closed again → immediately goes back to 4,000+ Kbps

Because of this, YouTube shows "Video can't load" / the stream becomes extremely unstable.


The strange part is that the problem happens only while VALORANT is running. As soon as I close the game, the OBS bitrate returns to normal.


My setup:​


  • Laptop: Lenovo LOQ
  • GPU: RTX 3050 6GB
  • OS: Windows 11
  • Streaming: OBS Studio
  • Platform: YouTube
  • Internet upload: ~49 Mbps

I've already tried:


  • Running OBS as administrator
  • NVIDIA NVENC encoder
  • Lowering OBS bitrate
  • Windowed Fullscreen in VALORANT
  • Limiting VALORANT FPS
  • Changing OBS settings

But the problem still happens.


Has anyone experienced VALORANT causing OBS upload bitrate to drop like this? Could VALORANT/Vanguard be interfering with the network connection or OBS somehow?


Any ideas or fixes would be appreciated.

Thread 'Please post a log with your issue! Here's how...'

OBS Studio creates a log file each time you run it which contains very useful diagnostic information. Without a log file, it's much harder for any support volunteers to figure out problems and your post may be ignored.

To upload a log file, go to the Help menu > Log Files > Upload Last Log File. "Last Log File" is for the last session (the last time you ran OBS). In some cases you may be asked to select "Current Log File" instead, which is for the current session.
