In many cases, wireless connections can cause issues because of their unstable nature. Streaming really requires a stable connection. Often wireless connections are fine, but if you have problems, the first troubleshooting step would be to switch to wired. We highly recommend streaming on wired connections.

OBS is not running as Administrator. Because of this, OBS will not be able to Game Capture certain games, and it will not be able to request a higher GPU priority for itself -- which is the likely cause of the render lag you are currently experincing. Run OBS as Administrator to help alleviate this problem.

Your GPU is maxed out and OBS can't render scenes fast enough. Running a game without vertical sync or a frame rate limiter will frequently cause performance issues with OBS because your GPU will be maxed out. OBS requires a little GPU to render your scene.

Enable Vsync or set a reasonable frame rate limit that your GPU can handle without hitting 100% usage.

If that's not enough you may also need to turn down some of the video quality options in the game. If you are experiencing issues in general while using OBS, your GPU may be overloaded for the settings you are trying to use.

Please check our guide for ideas why this may be happening, and steps you can take to correct it: GPU Overload Issues.

Encoder overload may be related to your CPU or GPU being overloaded, depending on the encoder in question. If you are using a software encoder (x264) please see the CPU Overload Guide. If you are using a hardware encoder (AMF, QSV/Quicksync, NVENC) please see the GPU Overload Guide.

One of the configured encoders is not recognised. This can result in failure to go live or to record. To fix this, go to Settings -> Output and change the 'Encoder' option.
