Question / Help Having issues getting smooth 1440p 60fps local recording on high end PC

Ok so I don't know if maybe my PC isn't as high end as I thought it was but here are the specs:

i7 6800k overclocked to 4.3GHz
EVGA GTX 1070 SC (+50/+400 OC)
Samsung 500GB SSD
Samsung 250GB SSD
2x 2TB HDDs
64GB Corsair 3000 RAM
Dell s2417 monitor overclocked to 165hz
HP 25 inch monitor (secondary)

In the Nvidia control panel, I turned on GSync and Vsync in the 3D management settings (at the suggestion of several reddit users). Apparently Gsync only works up until your monitors refresh rate and then tearing occurs.

I turn off vsync within games. This gives me pretty much consistent 165FPS in my games. When I record (or just play) the movement is incredibly smooth. When I watch the video back, it looks no where near as smooth. It looks like it's running at 30FPS (or worse).

Have I simply reached the full capabilities of my computer? Or OBS perhaps? Local recording is my main priority.

Yes sir I have. I've tried both NVENC and x264 at varying bitrates. I've tried using CQP 15, 20, 22, 25, and even 0.

I'm wondering if maybe the discrepancy between the amount of frames my comp is displaying vs the amount that's being captured is causing the problem. Should I perhaps use Nvidia inspector to limit my framerate to 60 that way it's consistent with the OBS settings?

Maybe. Other threads advise fixing ingame max FPS to VSync, or 60 -generally VSync=60-. Win10 Anniversary has some problems when you try to get maximum performance from your graphics card.
 
Hi,

You current settings are

2560x1440
19:55:02.429: rate_control: CBR
19:55:02.429: bitrate: 75000

Swap them to the following

2560x1440
19:55:02.429: rate_control: VBR
19:55:02.429: bitrate: 50000

then see if that smooths out the playback and tweak if required to improve the quality.

Ok thanks I'll give it a try. I tried CBR 50000 at one point and it was a similar results. I'll try VBR and bump up the rate.

I'm also going to try the 60 fps limiting within game.
