Quickly running it through the log analyzer I get the following to errors:
Multiple video cards detected
If you are having problems and are using a laptop, see
this thread for advice.
If you are using SLI or Crossfire, you may need to disable it for compatibility with OBS.
Bad resolution / FPS / bitrate combination
The combination of settings you are using will likely lead to a low quality stream with artifacting and other problems.
Consider either raising your bitrate or lowering your resolution / FPS (qval: 0.016)
2 issues found (1 major, 1 minor).
Not sure if it will help much but make sure to set the "
Max Bitrate (kb/s)" and [if needed] set "
Buffer Size (kbit)" to both be
3000 (if you're streaming online to Twitch.TV or something similar) and see if that helps. Those options are found under "
Encoding" within the "
Settings" window.
Also, under "
Video" make sure your main video card is chosen for "
Video Adapter".
Let me know if either those help or if you need any further help/info.
