Question / Help QS and NVENC stream/recording - huge FPS hit

I've recently bought GTX 960, which I thought would be a great GPU for my needs after having a little bit of fun with GTX 980.
On GTX 980 I was able to stream and record 1.5Mb/s 1080p60fps using QuickSync with no hit in performance WHATSOEVER!
Now on GTX 960 trying to use the same settings for either recording or streaming and Quick Sync or NVENC, yields the same results:

In AssettoCorsa FPS drop from 290-300 to barely 150-200 (resulting in huge stutter), second monitor (Intel igpu) is unusable (5 FPS and huge delay at best), either PC crash at start or after 2-3 minutes. + people say my stream looks smooth.
Temperatures are not rising above 50 for GPU and 60 for CPU. (CPU is overclocked to 4.2 GHz)

What should I do?

My setup:
2x4GB + 2x8GB=24GB of DDR3 RAM
i5-4670K at 4.2GHz
Intel HD 4600 at 1.2 GHz
Gigabyte GTX 960 4GB non-overclocked

THESE ISSUES ARE FIXED!

well i know QS uses iGPU in CPU as an API.. also is it just me or are ur intel graphics running high? 1.2GHz? if thats overclocked, that will drain CPU power a bit, have to balance that out. if ur going to over clock anything, heres my suggestion, OC the CPU to turbo speed, and OC the GTX 960 a bit, its a modern card so it shouldnt suffer too much extra heat. also your memory is it interleaved? meaning varying speeds/brands/clocks/types/channels? as in just stuck in there or did u properly allocate it into appropriate slots so channels matching? shouldn't make a big difference but bandwidth is bandwidth.

ok so assuming you followed directions posted for best quality recording and streaming.
trouble shooting 101;

dont use second display, check see if it will behave better if so, see if u can run it from the dGPU instead. if not, next step.

save bios profile externally or remember it, then reset it, check see if it behaves better. if so, flip things back see what causes it. if not, revert it back to your setup, then next step

disable overclocking on iGPU and unplug monitor from it , see if it behaves better. if so keep it as such, or test it with monitor without OC. if it becomes problematic with second display, that's hogging limited resource. if it isn't fixed wither way, continue down..

remove the 2x4Gb of memory (16 GB is more than enough for this), see if it behaves better. if so, buy more matching memory if you need it.

finally test using shadowplay(a GTX 900 series feature you can download form nvidia), if it doesn't behave nicely, your video card may be problematic or drivers may be problematic. ..sort from there.

Connect both of your monitors to the nvidia gpu, that should atleast fix the second monitor lag issue.

could also be the issue, though i never experienced that on my APU's iGPU using second screen, it always remains clean and clear and smooth as normal on both....
then again i cant effectively even capture, it always looks like sh.t... but ya..he/she/it has a point, its usually prefered to use dedicated gpu for second screen and i think only reason its smooth and uneffected for me is my components are all HSA based so all work together and share resources cleverly... just wish it could happen in other ways like...ok i said it enuff...but capture via iGPU >:(

*shrugs*... ill just..be over here..

Do you think this quality is good for 1080p60fps 1.5Mb/s?
Or can I improve it with ShadowPlay, NVENC? (I'm not willing to switch to CPU coder)

Same settings, GTX 980:

QUALITY IS WAAAAAY BETTER! WTF?!

Edit#2
I think I got it.
Is having buffer so bad? Cause I think that rising it up fixed everything (But I can't check it right now)

Im sorry, fixed.
Can you look at both videos, having the second one as example how it should look and the first one how it's now.

Issue fixed (I guess) with switching to 32-bit OBS, overclocking iGPU and disabling paging-file.

I've also taken out 8GB of RAM and connected both monitors to dGPU which I will check if possible to change.
