Lowered FPS in-game while streaming

[bigshant]

I've been trying to start streaming League of Legends, but every time I do my FPS drops down to around 50 fps and it looks very glitchy so I can't play very well. I don't know if this is because of the CPU I have or it's because of my settings.

I have an i7-9700k at 4.8Ghz and an RTX 3060 Ti.

the tips from cycle are all good and fine to improve , but the problem you report of 50 frame in LOL with 3060TI on i7-9700k at 4.8Ghz
sound more like you use x264 CPU encoding that "overload" the cpu and results in less game performance
the 3060 have nvenc that can handle the encode close 0 fps loose
3060 easy handle at 1440P 144+ fps if the CPU is not limit the frames
