OBS makes my cs2 have freeze's

[HLEB]

Hi, I’m a professional Counter-Strike 2 player and I’m trying to start recording/streaming my gameplay. However, I’m running into a strange issue:

As soon as I launch OBS or Streamlabs, my game starts to stutter or micro-freeze, even though I’m not recording, streaming, or doing anything with it.
Just having OBS open causes frame hitching.

My System Specs:​

• CPU: AMD Ryzen 7 9800X3D
• GPU: NVIDIA RTX 3080 (latest drivers)
• RAM: 32GB DDR5 @ 6000MHz
• Monitor: 1080p @ 240Hz
• Storage: NVMe SSD
• OS: Windows 10 Pro

Things I’ve Already Tried (none of these fixed it):​

• Game Capture, Display Capture, and Window Capture — all same result
• Turning off Game Mode, and overlays (Steam, Discord, GeForce Experience)
• Running OBS as administrator
• Turning off Preview in OBS
• Clean OBS install
• BIOS settings checked — no PBO/EXPO instability
• Tested both with and without scenes/sources
• No plugins installed
• Updated all drivers and Windows
• Disabled all startup apps
• Same behavior in both OBS and Streamlabs
• Installed windows again

Everything worked normal in january when i streamed last time.

Does anyone have any suggestions? Thank you!
