Technical stream problems, looking for help

Hi!

First time streamer here, and I have a few issues with my initial stream testing.

I streamed PoE and everything was perfectly fine except 2 issues. Firstly, although my in-game FPS is always 60 (v-sync), it dropped to flat 30 while streaming. Now, this wasn't your sudden FPS drops associated with straining your CPU and/or GPU. It was a constant, flat 30 FPS, as if the fact that I was streaming somehow limited the FPS to 30. I did set the OBS encoder to stream 720p @30 FPS, but that should not change my in-game FPS, right?

Secondly, although I have a 5Mbps upload link, and the max bitrate is set to 3300, my latency changes from a stable 48 to 60 with spikes up to 120. How can it be possible that a 20M download/5M upload link isn't enough to stream in 720p and not have an in-game lag? I used to play PoE with a 0.5M upload link with a stable latency (without streaming, ofc). Is it possible that 4.5M isn't enough to stream at 720p?

Thanks a lot!

This is Xsplit page, but it applies to OBS all the same. Check the tables:

If you are in the right range, it is all about OBS configuration or video card drivers. Also, check other stuff needed by OBS. Your rig specs would help, too.

Thanks, I managed to get some help on OBS forums as well. The problem was I was using monitor capture instead of game capture, that's why my FPS dropped. Although, now when using game capture, my camera isn't shown...

As for the latency, I discovered I have lowest ping to twitch amsterdam server for some reason, instead to prague, which is half as far from me geographically as amsterdam. Funny. Same as PoE beta servers, in fact, amsterdam being better than frankfurt.
