My game is lagging while streaming, and I’m really struggling. Can you please help me

[stephixex]

When I play my games without streaming, everything runs perfectly fine. However, once I start streaming, everything falls apart—everything starts lagging. For example, in League of Legends, I get kicked from the game. I've already tried game capture, screen capture with fullscreen/windowed mode, etc., but the issue persists. Attached is the log file from my last stream. It's weird because everything worked perfectly a few streams ago. Please, I’m desperate for help!

my personal experience from years of watching this forum... if you want reliable don't use/touch streamlabs... at all. period..
Some people get it to work ok... and may not be your issue... but look at your log. ugh, I really detest sloppy code that pukes all over the OBS Studio log..

Anyway... I don't know exactly why
1. run your log through automated analyzer to see if it finds anything (see my signature for link)
2. look into prior discussions of screen refresh rates to screen capture rates... 60 fps and 240Hz refresh is an even multiple... the 75Hz screen - not at all ... never recommended to have uneven multiple like that. whether that is relevant, I can't say....
3. mixing color format - not usually advisable

4. normally this means... fix your network

18:53:16.174: Output 'rtmp multitrack video': Number of dropped frames due to insufficient bandwidth/connection stalls: 20592 (20.1%)​

but in this case, I'm guessing CPU overload causing lost/dropped network packets?? though I'm guessing it is some of your encoding settings, leading to overloaded GPU encoder

Check your cables. Ditch the multi-out until you get it figured out.
