Can anyone assist me in why things are appearing fine on my end, but lagging on stream. I am considering the possibility that I may need a VPN to fix the issue. I'm not dropping any frames when I stream, but I don't get the greatest ping or jitter with R1CH's JTVping to any server.

you're duplicating a lot of frames - the encoder has to "fill up" the blanks which it does not receive to keep framerate up, this might be because the game itself you're playing is running at a lower framerate. Consider dropping fps back to 30. You probably want to have the preset back to veryfast too. I don't know what game are you trying to capture, but in most cases there is almost NO visible difference between veryfast and faster, but the latter does cost noticeably more processor time.

If you experience lag watching your stream, but local/twitch recordings play back fine - it is probably: a) twitch itself. That's how it is these days, quite often you just cannot get a stable stream off them b) unstable internet connection, in this case freezing should be obvious from watching the stream archives on twitch. Your logfile indicates nothing of that though.

P.S. I've watched the latest recording on your stream and the problem is definetely a client side, meaning yours. From what I've seen in the recording, you will have to: a) move preset back to veryfast b) reduce encoding framerate Good luck!

Yeah, I noticed that, but I still duplicate frames when going back a preset, dropping bitrate, dropping frame rate, and all 3 combined. I;m really confused. The game is playing at 61fps capped, and being fed into my livegamer HD capturing at 60fps. I'm not really having any cpu issues, like high usage, dropped frames or anything like that, which has me perplexed as to why it's duplicating frames :(

Thanks for your reply :)

Have you tried excluding your capture card from the equation and capturing with game/window capture? That might hurt performance, but you could check whether the freezes are still there.

I am using a 2 pc setup at the moment, but I can try and put a low end game on my streaming rig and give it a go when I get home from work. I had it set up quite well a while a go I think, and then had to format due to a corrupted boot drive, and I feel I never got it quite right since.
