Fraps and the in-game FPS counter never drops below 100 fps (I think) but when I'm playing it feels like 25-30 FPS and the stream shows it as 25-30 fps aswell.
I did a short test with Game Capture instead of Software Catcher and it seemed to increase the performance a bit, but it could also be that I lowered the Quality Blanace from 10 to 8.
I really have no idea what I'm doing, so if anyone could just like help me with what settings would be optimal for me I would greatly appreciate it.
Thanks!

First of all if you are playing games always use game capture or Window capture since Software capture is the worst of all for your overall performance.

Try to lower your fps to 30 also don't use CBR and CFR it won't make your stream better but more likely worse. Also try to use
Low-Latency-Modus in Broadcast Settings since your ping is not stable.

If this doesn't help try to downscale to 1280x720 and set fps to 60.

Thanks, I'll try changing some settings after school,
however I don't want to lower the fps or quality since I think my net/pc should be able to handle it.

And about the ping, it is normally stable (fiber), I think I was patching neverwinter in the background which may've caused the weird ping.

Also 1080p @ 60fps will mostly cause lag because flashplayer can't handle it. I recommend setting fps to 45 or 30

I got it pretty stable at 60fps and 1080p now, but I do notice some instability in the ping still, never really settling and jumping up and down even though I now had no background interference.
Since it never really goes above 60 ping I don't really notice any lag or ping impact while playing so it's not really a problem, but what settings in the OBS have an impact on ping?
I mean, if there is something I can do to stabilize the ping without killing the quality or performance of the stream I'll of course happily do it :)!

The low-latency thing under Broadcast settings were enabled during the stream btw.

Click to expand...
just about everything. the major ones are the quality setting, the resolution. the bitrate and the bufsize. ping is only a problem if you think that it effects your game play in a very noticeable way.

i've also had really much frames droped yday on my new system, i5-3570k.. 15% of total on 2h stream.

Is it the connection to the twitch or is it my buffer settings as Kaninstek said?

it depends. when he tells u it lags go and cehck obs and if ur not dropping frames and everything looks perfect chances are its a server side issue. even on some of the best streams people sometimes get that video only lag becuase twitchs servers suck.
