Question / Help stream lags and skips but game is fine

[coltezeu]

http://www.twitch.tv/offq3/b/410609038 and there is the log for this video attached.
anything under faster preset starts lagging my stream like hell , but my game performance is flawless... what to do?
i cant stream on higher than fast because the quality is shit, tried increasing the buffer to 5000 and 7000 still the same...
i have a good pc : i5 3470, gtx 660 , 16 gb ddr3 1600mhz, any suggestions?
i have 85mbps download and 80mbps upload to frankfurt stream server

Why did you disabled Multithreaded optimizations? Also a slower preset means more cpu pressure, normally veryfast is fine.

 

[coltezeu]

if i enable multithread optimization my game starts to lag and theres no change to the stream what so ever so i left it unchecked.
check out veryfast quality http://www.twitch.tv/offq3/b/410604182 its unwatchable

Change the preset back to veryfast and reactivate MTO then pick amesterdam or london ingests instead, (frankfurt is not the most reliable).
For more quality you wanna increase the bitrate first instead of using a slower preset.

Coltezeu:
Are you sure those speeds are accurate? Reason I ask, I just heard that fios here in the US max rate is 300 mbps down, and 60 mbps up. You posted that you get 80 mbps upload? If that is true, then the US needs to catch up :)

Don't use the Frankfurt server. It is overloaded and known to have slow connections.

on a related note, whats the difference between using obs's default game capture and having a hardware capture card?
is there noticeble quality difference?/performance difference?
if so , if your capture card supports 1080p/720p and not @60 fps, can you still stream @ 60 fps?

Game capture captures from the PC you're playing on, a capture card captures a different PC.

 

[coltezeu]

i mean you can stream with obs without having a "avermedia for example" capture card with its default software but you can also stream if you have a capture card installed in your pc, whats the difference between the two methods

 

[R1CH]

I'm not sure how else to phrase it, the only thing it changes is the source of the input. A capture card takes the screen from a different PC, software / game capture captures the PC which OBS is running on. Technically you could loopback capture your own PC with a capture card but that's negating most of the benefit of it in the first place, which is not having to encode on the same PC you're capturing.

you are not the only having this problem with OBS.

no matter what i do. I can not get the stream to run fine. I lower all my settings. I change twitch servers. Nothing.
