Hello Everyone,
This is my first post and not my last, as I've read lots here, and been a user of multiple programs, but OBS takes the cake of flexibility to myself. I know the title is long but as of late I've been running into issues with any game I play, even if its a basic 8 bit or 16 bit game. I use OBS remote to monitor my stream on on my cpu, now keep in mind this CPU is not the lambo of cpus, but it does great, and I do what I can with what I can. Prior to re installing my OS (Which is a valid copy bought from new egg originally), and re installing drivers to get everything working with my asrock MB, I've had and issues with FPS dropping on my stream. Sometimes it will run from a consent 30 to all of a sudden a tip down to 15 or 2 fps for no reason on my stream. No warning on for slow encoding etc. in obs as I do watch it like a hawk. Prior to my OS install, my OBS ran perfect with no issues or FPS drops, I even removed majority of drivers, or rolled back some that are pre installed or "recommended for the Asrock MB I have" I've attached a log file of my most recent stream that did have a drop in FPS. I'm at a loss I've have tried all the stickies, scripts, re installs, updates and everything of OBS, including changing to downsizing 1.5 times and the encoder other then something from "Very Fast". Also, my speed is more then capable enough to hand streaming at 1080p most nights. I've ran speed test multiple times during week days to a lot for fluctuation in network due to being on cable. Any help would be appreciated, and I can provide previous logs past to night if needed.

My down is avg 60 mbs/s
My up is avg 30 mbs/s

Downscaling should do the trick. The problem is that CPU isn't actually a true 4-core, it's a 2-core, though hyperthreaded. I see some skipped frames when you're trying to run at 1080p. I feel like that may be part of the issue.. I'm not sure if you should really be tryign to push out 1080p on that CPU.

as add to this post ran most recent log file through obs log analyzer this is what it stated.


Late frames detected

50.00% of your frames are late. This means the frames are being generated later than they were needed, causing your stream FPS to drop. Late frames are often caused by slow sources such as monitor capture, slow video capture devices or by trying to run your stream at too high of a resolution / FPS.

If you are using a webcam, try to lower the resolution of it. If you are using monitor capture, try switching to game source or window capture. If you must use monitor capture, ensure Aero is disabled.

You can also try lowering the resolution or FPS of your stream if you have an older CPU.

See https://obsproject.com/forum/viewtopic.php?f=5&t=11641 for more information on how to resolve this issue.

Possible slow server

The server you are streaming to (rtmp://live-iad.twitch.tv/app) took 519 ms to connect. This may mean your connection or the server is slow, or the server is far away from you. If you are using twitch.tv, you may want to try using JTVPing to find an optimal server.

Monitor capture detected

One of your scenes appears to be using monitor capture. Monitor capture is the slowest and least efficient method of capturing, and can cause FPS lag on both your stream and your game and will also cause problems capturing full-screen games. Consider using game capture or window capture instead (this does not apply to Windows 8).

Monitor capture with Aero enabled

You are using monitor capture with Aero enabled. This will cause severe performance degradation. If you absolutely must use monitor capture, disable Aero from video settings (this does not apply to Windows 8).

Low frame rate detected

Your stream is taking an average of 58.609 milliseconds to render a frame. This limits your maximum FPS to around 17 FPS. The most common reason for long frame rendering times are:
    • Using monitor capture
    • Using slow devices such as webcams running at 1080p
    • Not enough CPU/GPU resources available for OBS
    • Running your stream at too high of a resolution / FPS for your computer to handle

@Jim ,
Thank you for the reply I've tried downscaling before. I'll try again tonight and generate a new log if I have issues.
