Stream lowers in frame rate when I'm dropping network frames

Well, if you drop frames you'll get stuttery playback, if that's what you mean? OBS wouldn't "slow down" or change the playback speed. Twitch may force the player to buffer additional video chunks if you're sending an unstable stream, if viewers are falling behind.
22:12:20.748: Output 'adv_stream': Number of dropped frames due to insufficient bandwidth/connection stalls: 12296 (1.1%)
It appears your connection is having an issue.
