Hello,

Twitch VoD: http://da.twitch.tv/pazia/b/360994783

Quality seems fine, but at times I feel like the FPS is a little to unstable. I have no in-game lag or stuttering and according to a CPU usage program I found, I peaked at like 50-60% at most, so there's some CPU to spare.

Any tips will be appreciated.

I think the quality looks great! However, you could use 30fps to improve your "stuttering issue." Also, for 30fps at 524p, you could use a VBV Bitrate of 2000, VBV Buffer of 4000 and quality of 8. Helps with the people who don't have the download speed to watch 3000Kbps streams.

I'll give that a try tonight, thanks!

Thanks for the input yesterday. I tried the new settings, and it worked perfectly but... According to OBS, I had a few frame drops yesterday. In 30-40 minutes, I think that the number of dropped frames were at around 3-400.

Noticed that the buffer were full at times. Should I perhaps lower the buffer-size at little bit for tonight?

You can see in the log file which version he is using, having a few frame drops is not a bad thing so don't worry about it. but for the buffer problem that your having i'm not sure.

You didn't actually drop enough frames to cause that big of an issue.

Usually for buffer messages like that, the first thing to do is try other servers. Especially on weekends, Twitch in Europe seems to get congested really easily.
