I have watched a lot videos and there are no videos that show how to stream first-person shooters with the elgato.When I do stream the video not as smooth as it should. Here are my settings for OBS.

Perhaps change the FPS to 60? Always give us a log file. Taking pictures of your settings is always less ideal than giving us a log file.

Do you have a vod that demonstrates the problem? Also, your FPS in OBS is set to 30. Perhaps that is part of the issue?

The stream quality looks fine given your settings and the video plays back smoothly. Increasing the bitrate (up to a maximum of 3500 Kbps for Twitch) will improve the quality but can cause buffering for some viewers the higher you go. 2000-2500 Kbps is considered the "sweet spot" for that resolution and frame rate.

You should enable buffering in the Elgato source properties, leaving the value at 0ms. If you're streaming console gameplay (i.e. your PC is doing nothing but streaming) your system is more than capable of encoding on the fast or maybe even medium preset under Settings > Advanced, which can also improve the quality. Changing the preset would be a better choice than increasing the bitrate.

You might want to consider changing the encoding profile from "High" to "main" not only is it what twitch wants you to do for your stream, it might help quality too
