OBS Not Working: How to Fix Common Streaming and Recording Problems

Everything you need to know about obs not working: how to fix common streaming and recording problems, explained plainly.

Step by step

How to fix it

Work through these in order, the most common causes come first.

  1. Black Screen on Game Capture

    The most common OBS issue on Windows. Right-click OBS in the taskbar > Run as Administrator If the game uses DirectX 12: switch the OBS game capture to "Window Capture" mode instead of "Game Capture", DirectX 12 has compatibility issues with some Game Capture implementations

  2. Dropped Frames / Encoding Overload

    CPU encoding (x264): high CPU usage competes with the game. Switch to NVENC (Nvidia) or QuickSync (Intel) in Settings > Output > Encoder. GPU encoding handles the same quality at a fraction of the CPU cost.

  3. Audio Sync Drift

    Settings > Audio: set OBS sample rate to 48000 Hz. Set the microphone or audio interface to 48000 Hz in Windows Sound Settings (right-click sound icon > Sound Settings > Device Properties).

Black Screen on Game Capture

The most common OBS issue on Windows.

Right-click OBS in the taskbar > Run as Administrator If the game uses DirectX 12: switch the OBS game capture to "Window Capture" mode instead of "Game Capture", DirectX 12 has compatibility issues with some Game Capture implementations On dual-GPU laptops: go to Windows Settings > System > Display > Graphics, find OBS in the app list, and set it to "High Performance" (forces the Nvidia GPU) In the OBS Game Capture source settings, enable "Allow Transparency" and "Capture Cursor" off, these can sometimes clear the black screen

Dropped Frames / Encoding Overload

CPU encoding (x264): high CPU usage competes with the game.

Switch to NVENC (Nvidia) or QuickSync (Intel) in Settings > Output > Encoder.

GPU encoding handles the same quality at a fraction of the CPU cost.

Network drops: if the frame drop counter is in the "network" category (shown in OBS stats overlay), reduce the streaming bitrate in Settings > Output > Bitrate.

Match it to your actual upload speed minus 20% headroom.

Audio Sync Drift

Settings > Audio: set OBS sample rate to 48000 Hz.

Set the microphone or audio interface to 48000 Hz in Windows Sound Settings (right-click sound icon > Sound Settings > Device Properties).

Frequently asked questions

Why does OBS show a black screen when capturing a game?

OBS black screen on game capture is almost always a GPU conflict, the game is running on a different GPU than OBS is using. The fix: right-click the OBS desktop shortcut, Properties > Compatibility > Run as Administrator, or go to Windows Graphics Settings and set OBS to use the High Performance GPU. On laptops with dual GPU (Intel integrated + Nvidia discrete), both OBS and the game must run on the same GPU.

Why are my OBS frames dropping during streaming?

Dropped frames during streaming indicate one of three issues: insufficient CPU/GPU for the encoding settings, network issues (internet speed lower than stream bitrate), or PCIe bandwidth limitation. Test by reducing stream quality settings (lower resolution or bitrate), switching encoding from CPU (x264) to GPU (NVENC/QuickSync), or reducing the streaming bitrate.

Why is my audio out of sync with video in OBS recordings?

Audio sync issues in OBS recordings are typically caused by mismatched sample rates between the audio source and OBS. Go to Settings > Audio and verify the sample rate (44.1kHz or 48kHz) matches the sample rate setting of your audio interface or microphone. Using 48kHz in OBS with a 44.1kHz audio source produces drift that gets progressively worse over the recording duration.
