When I stream via Xbox I am only getting 46 fps max on a 60 set. To make it stranger I only get 58 fps on my pc. WITH A GTX 680!

Encoding video is actually CPU-bound, not GPU-bound. From what I can see in your log, a lot of frames are lagging when trying to be encoded. According to the profiler, the encoder can't keep up with 60FPS.

Try setting your preset to veryfast...generally you don't need to change from that preset at all, and going from veryfast -> faster introduces much higher load on your CPU. You can also try lowering your frame rate, too, if that doesn't help.

Also, I see you're capturing with a BlackMagic device...which one are you using?

I also see that his bitrate and buffer is really low too. Depending on the quality he is trying to achieve, he might need to raise that if he has the upload bandwidth for it.

Also, you only have 4gb of ram? That might cause issues.

Use that as a guide.

i have 8gb of ram

i also have a i7 sandy bridge @ 3.4

i have 40 down and 25 up

edit:

I get about 160fps on Borderlands 2 and once i launch OBS it falls to 57

That's really weird :S
I'm using a worse setup than you (i3, 8gb ram, radeon hd 6670) and I go from 100fps in smite down to 70 with OBS streaming.

This shouldn't have any effect, but have you tried lowering your in-game graphics to test if maybe that's the problem?

I have a gtx GeForce 680 FTW my graphical settings should not be the issue.

I also want to point out that i am getting 25 MAX fps with the window capture function on obs.

Please make sure that you do not have a lot of unused global sources in your global sources list.

Even if they're not used in the scene you're currently previewing, they'll still be active and might be causing extra load depending on what they are.

I have never used Global sources. I have been streaming since The FME era 2009. I have used Wirecast, FME, xsplit and xsplit before it got redone. Never had this kind of fps lag on wirecast or others just OBS.
