Having too many apps open in the background is one of the main reasons why you may face many app and feature issues on your system, and Teams Video latency issues are another common issue. It is known that applications like Chrome or Skype consume the highest system resources such as RAM and therefore slow down other applications due to less available RAM.

Also, to make high-quality video calls, you must have a high-speed internet connection, and the Teams app requires a high-speed connection. Therefore, if you are running too many similar instances at the same time, such as downloading media files or large files while streaming videos or music, you must consider temporarily pausing the downloading or streaming process. This can help you continue video calls on Teams temporarily without any hassle.

However, sometimes certain Windows features may interrupt video call performance, such as the microphone, so if you are not using the microphone for a while, you can try disabling it, which may help to temporarily solve the problem. Alternatively, if it's not urgent, you can also try disabling the video and avoid any video lag issues.
