Ok so I currently have a dual PC setup, and on the gaming rig I get a solid 144 fps and things are super smooth as if I wasn't streaming obviously because the load is on the second pc. The Streaming PC is set to have 720p 60 fps but I noticed that at the bottom of OBS where is has the bitrate you're currently at FPS etc, the fps is usually only at around 35-37 range which I'm guessing should be at 60? I am using an avermedia to capture it and I did a local recording and the video turned out kind of choppy/not as smooth as I would like, any ideas how to fix?

downscale

Try a different filter. Had the same problem and that fixed for me.

What avermedia are you use?

Don't use a custom buffer size.
That Radeon 3000 is ancient, and may very well be causing issues; OBS uses the GPU for scaling and composition of the final frame, and older cards can have speed problems. I'd probably do a Fry's/MicroCenter "rental" if it was me, to see if a modern budget-grade card would fix the problem.

You're duping a significant number of frames. Anything over 1% should be looked into. I'd recommend turning off CFR unless you plan to edit a locally recorded copy later with Sony Vegas or another tool that requires CFR. Twitch does not (they need CBR, not CFR).
You're also running relatively close to the video thread frame limit for 60fps (need to stay below 16ms to achieve 60fps, preferably significantly less, in the 5-7ms range).

Failing all that, OBS and Windows 10 generally don't get along in many cases due to changes MS made (and continues to make in new patches). There's a reason most production environments tend to wait at least 6-18 months before even considering a major upgrade, and leave the weird problems to the early adopters.

Thanks for the response, I tried changing what you said, minus the graphics card and literally nothing changed, I don't think windows 10 is the problem because I tried running the 720p 60 fps on the gaming rig and it worked okay, so I am guessing that its the graphics then, right now I am just using the onboard graphics on the streaming PC because I thought I could get away with it, by budget-grade would you say something like a gtx 560 would do the trick? Thanks

Could also be something funky with the capture device. Know a few had problems with older motherboards that only had PCIe 1.0 slots, when their cap cards needed PCIe 2.0 (each PCIe revision increases the bandwidth per channel by 4x, so if it's expecting a PCIe 2.0 1x slot but only gets a 1.0, it'll be bottlenecked by bandwidth hard). Speaking of which, have you tried capturing video with the cap card's own software, and seeing if it had visible framerate issues there?

Tried playing a game on the streaming machine itself to test?
I'd probably go for a cheap passively-cooled GT 730 or similar, if it was me, and the streaming machine can't swing 60 on its own.

To clarify, I'm looking at your video card with a hairy eyeball both due it its age, and this line from the log:

Well I just checked my motherboard and it does have pcie 2.0, not 100 percent if its actually plugged into it, but I tried updating the avermedia software because I thought that might be the problem and it went from saying 37 fps to around 45 lol, I do recall when I was setting up the machine that the amd driver didn't update or something like that, but the fps increasing makes me think that its the card, thoughts?
