Hello, I am sorry I am asking, since I already found some threads discussing about that, but I just wanted to have my question double checked since I am not quite sure if I understood everything correctly. I just wanted to ask about a scenario of buying a AverMedia capture card. When I am streaming OBS says that my CPU is using too much power encoding and my game is laggy. I have tried to lower the preset and fps, but it didnt really help. Then I remembered there is an option to buy a capture card. But when I did a bit of research I found that capture cards didnt really help you with this problem at all if I understood it correctly. I thought that capture cards are supposed to help you with streaming because the majority of the power needed to encode a stream is done by them and therefore they are saving a lot of CPU power for the game. So is buying a capture card a valid option for me or not? Thank you.
 
OBS cannot use the encoders on Avermedia capture cards. It will not help you. Do not waste your money.

Better idea, post a logfile from a test stream from the Help menu, and we can take a look and see what needs to be done to fix the settings. :)
 
This a log from my last stream. By the way. could you please help me with like all the possible solutions that I can make in order to avoid my laptop streaming? Like can I play on one PC and stream with the second one? Or can I use a capture with some other software? Or is OBS compatible with some other capture cards?Thank you. :)

That CPU should be able to handle 720p@30fps, x264 Veryfast no sweat. Check if you're in a lower-power or power-save mode; the OS can park or throttle cores to save power, when you need everything you can get while livestreaming.
 
I have already checked. My laptop is running on "high performace mode" so there should be no problem. Stream is moreless smooth for viewers, but the game experience spikes when i am streaming .. The weird think I have noticed is that my CPU is actually running only at 60-70% of its power with just some rare spikes to 100% while streaming.. Maybe the problem lies there. Why doesnt it just go to 90-100% to provide more power when it is on highperformance mode? I even tried to clean the registers.
