Hello there.

I've been trying to get this whole streaming thing going on, i think i managed to get a good bitrate (I've got 8mb upload speed, i could probably bump it from 1000 to 1500?) and probably not so poor video quality. The problem is even though i manage to achiev over 60 FPS ingame (this using GameSource as my main capture device) i still somehow stutter, could this be an issua with my CPU?

It's hard to tell for sure, since your logs are of very short streams. Your CPU should be able to handle 720p at 30 frames per seconds, if only just barely, you might not fare so well with games more demanding than LoL. However, what is causing your stutter is most likely that your frame rate in LoL isn't capped, I see it going over 100 a bunch of times in that VOD of yours. OBS does scene rendering on the video card, and if something else is using all of the video card's processing power, this will result in stutter, lagged frames. Try keeping your FPS in LoL capped at 60, if possible.

Hmm, i'll try that and i'll try to do a long stream session later on to see if it works better or such.

Thanks for the quick reply.
