Recordings of gameplay have stutters/fps drops

[comicoff]

Hello,

As title say. Sometimes recordings are smooth and fine but sometimes the issue mentioned in the titled occurs.
PC specs:
-I7 8700
-GTX 1080
-16gb RAM
I am using 1080p monitor with 120hz refresh rate. Though i use RivaTuner to cap FPS to 60. Vsync is off. FPS in game is constant, perfect 60. I used Nvidia shadowplay and OBS and with both i get the stutters.

Recording settings: 1080p, 60fps, 50Mbps bitrate.

Fixes that i tried:

-Clean install of drivers using DDU.

-Clean install of Windows 10.

-Lower bit-rate.

-Record on an external HDD.

I would appreciate a lot if anyone can help me with this frustrating issue.

Here at 0:08 when character jumps is an example. Right after the first jump, is a second jump so you can compare the jumps to notice the stutters.

To clearly see the stutters watch it on open the video link in a new tab and watch in fullscreen.

 

And here you can observe the stutter trough the video.

Thanks!

Doesn't help at all, because it's impossible to say if it's from the Game, or your System.

 

 

Download MSI Afterburner, let it Run in the background to log everything.

Then play abit untill this "stutter" appears, and screenshot or save the Logs (ALL of them, not just the first page). If you can, go into settings --> activate all the things that can be monitored. some are disabled, like (i think) Framerate and Frametimes.

 

I want to see how your fps and frametimes look like in that situation, and what the rest of the System looks like. maybe something is bottlenecking somewhere.

 

Do you record on OBS with your CPU or GPU for encoding?

I will do it. Need to mention, the game do not stutter at all, only the recording does and in OBS i use the GPU for encoding.

 

 

Here is another example, untill 2:05 the recording is fine 60fps, after 2:05 it looks like it was recorded in 30 fps.

Use CPU encoding, if you're on an 8700 there's no need for GPU video encoding.

Here is the log from the last recording.

ooh only the recording.

 

The Log looks pretty damn good, and should not have any issues there.

 

Even GPU usage is never at 100%, so recording SHOULD have no issues. But it could always happen.. software stuff etc.

 

Change the recording / encoding / anything in OBS to CPU calculation, and NOT GPU, and try again. Maybe it's related to recording with GPU computing itself.

Ok. I tried the CPU encoding and the recordings still stutters !!!

I don't use shadow play but as some one who has done a lot of video and audio editing -quick question:

Are you using compression -if so and possible try turning it off.

[comicoff]

Shadow play do not have such option so i guess no.

First thing I would try is removing the FPS cap via Riva Tuner.

Then higher bit rate and a lower resolution if that doesn't work.

I fixed it. I had to limit the fps with nvidia inspector. If someone have this issue just download nvidia inspector, limit the fps to your wish and select a limiter mode that will work best for you.

 

Thank you all for trying to help me with this issue.
