I use OBS for streaming in youtube ,same setting on 2 computer spec
OBS Setting : x264 ,cbr ,maxbit 7000 ,audio aac 128 44.1kHz , resolution from source or 1280×720p ,45-60fps
advanced : use multitheaded opt , Process Priority above normal , x264 cpu preset: superfast ,encode : main
keyframe : 4 , use CFR
--------------------------------------------------------------------------------------------------------------------------------------
spec 1. GTX 960m 4GB , i7 6700HQ 2.6GHz , Ram 8 GB 1980x1080p window 10

I'm not one for reading logs but maybe I could attempt to help, better than none.
Here are possible suggestions/thoughts.
- Your OS always could play a role, not just how it functions but what you have installed on your system. If you could, limit anything that you think could be affecting OBS, hard to say since I don't read into logs so this is just a toss. I still haven't had anything too much to say about Windows 10 except I would love to have Windows 7 back.
- Your resolutions are different, I'm assuming your second pc is maxed on resolution perhaps? What if you lower your resolution on your game to match your secondary pc's specs. I don't know much about geforce optimal so I have no idea how this works.
- On your second pc, look at the top log and compare to the first. Could the CLR browser be affecting the stream quality? Differences in logs.

Overall though, I know I just threw around ideas but possible look into software on your system, os potentially since it's hard to test since you've already established your windows 10 os and windows 8 os. It's so strange since it's only 4gb also and with the processor being lower than the i7. Strange.

For fun I'll look into this more but if I don't find anything then I won't post about it probably. Good luck and continue testing

Ok so right off the bat I found some notable things you should look into a little bit more.
I'm not an expert but here are some things that popped out that we could consider.

Specs 1
Adapter 1
23:00:19: Video Adapter: NVIDIA GeForce GTX 960M
23:00:19: Video Adapter Dedicated Video Memory: 3221225472
23:00:19: Video Adapter Shared System Memory: 1073676288
23:00:19: Video Adapter Output 1: pos={0, 0}, size={1920, 1080}, attached=true

Specs 2
22:03:00: Adapter 1
22:03:00: Video Adapter: NVIDIA GeForce GT 635M
22:03:00: Video Adapter Dedicated Video Memory: 2092494848
22:03:00: Video Adapter Shared System Memory: 1815660544
22:03:00: Video Adapter Output 1: pos={0, 0}, size={1366, 768}, attached=true

There is a considerable amount more of shared memory on your second device than your first. Possibility?

The second thing that grabbed my attention was

Specs 1
Video Encoding: x264
23:00:19: fps: 60
23:00:19: width: 1280, height: 720
23:00:19: preset: superfast
23:00:19: profile: main
23:00:19: keyint: 240
23:00:19: CBR: yes
23:00:19: CFR: yes
23:00:19: max bitrate: 7500
23:00:19: buffer size: 7500

Specs 2
Video Encoding: x264
22:03:53: fps: 45
22:03:53: width: 1364, height: 768
22:03:53: preset: ultrafast
22:03:53: profile: main
22:03:53: keyint: 180
22:03:53: CBR: yes
22:03:53: CFR: yes
22:03:53: max bitrate: 6000
22:03:53: buffer size: 6000

Here we might have found our problem. Take a look and see how the encoding actually isn't the same when it starts up your stream.
So what we need to do is copy your encoding settings from Sepcs 2 onto Specs 1.
Whats Different?
1. Fps, fps on spec 2 is 45. On your main device w/e it's 60. Theres one.
2. I'm not gonna worry about width and height, this is fine.
3. Presets are different, this is encoding but if it has anything to do with the stream and the speed, ultrafast produces a larger file but gets the job done... faster. Try matching this
4. Bitrate, this is where it gets tricky/fun. Your bitrate on the main machine spec 1 is higher than spec2.

Overall, let's try and match your settings from spec 2 and set it to spec 1. Post a log of spec 1 after that and see if they match or post here if you want me to take a look. Hopefully we can figure this out.

Generally speaking (or is it typing?) when a log isn't posted, their post drops to the bottom of the queue for me, and I have been quite busy. That said, thank you for posting a log (actually 2).

Abszol pretty much pointed out the differences between your settings on both systems, so I won't cover that ground a 2nd time.

My comments are:
1. The Shared memory amount isn't anything to consider/worry about.
2. Ultrafast uses less CPU then Superfast.
3. If you turned up the settings in Overwatch (which is a bit of a CPU and GPU hog) it can cause a faster/better system to run at a lower frame rate. For the purposes of comparing the systems and their performance, you'll want to try and run both games at the same settings, or as close to the same settings as possible. Of course after you're done comparing the 2, you'll want to increase your settings back to a good level of performance+visuals.

You claimed both PCs were on the same settings, but the OBS logs prove otherwise. Therefore your claim that your high-end laptop is not smooth while your low-end laptop is smooth, is invalid. But you deceptively got a lot of people to look at your thread, so there's that.

23:02:55: | GPU download and conversion - [96%] [avg time: 16.895 ms] [children: 0.591%] [unaccounted: 95.4%]

I'm not great at looking at the profiler, because there's no documentation on it. But I think this is your problem. Your GPU is running too slow. Make sure your GPU drivers are up to date and revert any recent Windows 10 updates. Actually do the Windows 10 reversion first, GPU drivers second, so that its done in the right order.
