Question / Help FPS drop

My friend drops FPS when he's streaming, the sound doesn't lag, he just drops FPS, he tried to stream in 25 fps/30 fps, he set keyint to 60/ then 30 then 50 then 25, still drops fps, he has 2 GB Ram, but I think he can handle 480p stream, can't he?

And he can't get rid of this error: Advanced Settings: Set keyframe interval of 2 seconds...

I'm confused, it worked for me like this before, now I have that problem as well, I think it came with the update 'cause it was okay earlier.

Btw, this happened to everyone who I know that uses OBS... It could be because of the update... everything was fine few days ago.

The link I posted in my first reply did include said information. Regardless, just copy the contents of the entire log to your clipboard (CTRL+A -> CTRL+C), go to pastebin.com, click anywhere on the large empty field, Paste (CTRL+V), hit Submit, wait for the page to finish reloading, copy the link (address bar) and copy that link into a message here.

... I said, post the link... not the whole log. :S

Regardless, that log shows both late frames as well as dropped frames. Late frames hint at the PC having trouble keeping up, dropped frames hint at the connection having trouble keeping up. Also, there is no more need to use keyint. OBS currently has a control to specify the exact keyframe interval without having to use a custom x264 setting.

Having said that -- don't use Monitor Capture, period. It is easily the slowest capture method and even if there are some configurations out there on which it does work, that PC is just too old to show any kind of respectable performance while using Monitor Capture. Just Enable Aero and stick with Window Capture or Game Capture or a combination of both if using multiple sources. That should take care of the late frames.

As far as the dropped frames are concerned -- run a test here, making sure to pick a test server that is near the server you have been streaming to. So an accurate maximum bitrate can be determined, because the dropped frames in that log are just completely out of control.

OBS still displays this error:
WARNING: Your OBS settings are not optimized for use with Twitch/Justin.TV. Please set the following: advanced settings: set a keyframe interval of 2 seconds.

The results are the same.

P.S. it only does this frame drops on Twitch TV, don't know why, but it does only there.

So, set the keyframe interval to 2 seconds.

Settings -> Advanced -> Keyframe Interval. Set it to 2 and remove any keyint you have specified manually in the Custom x264 Settings.
