Question / Help OBS doesn't record in 60 fps

[DaiBi]

I am using OBS to record gameplay footage and recently i start to notice that despite settings, the recording is made in much lower fps than 60. Output files properties shows 60 fps, but i can clearly see that it is not true. NVIDIA shadowplay f.e. works just fine and make true 60 fps recording. But i really like the OBS, so please help. :)

my specs:

win10, gtx970

 

[DaiBi]

OBS Log Analyzer shows astonishing 46.21% late frames! But why? My game run at 100 fps.

 

[Harold]

What your game runs at and the resources OBS uses to record are separate.

Post your OBS log.

Your system isn't capable of recording at 60fps as long as it's not possible to get the frames off the video card in less than 16ms.

What pci-e mode is your video card running in?
What driver version are you using?

 

[DaiBi]

Your system isn't capable of recording at 60fps as long as it's not possible to get the frames off the video card in less than 16ms.

But shadowplay works fine. And i did 60 fps recordings before with my current system and OBS.

What pci-e mode is your video card running in?

Mode? Where i can see it?

What driver version are you using?

Latest. 372.70

 

[Harold]

the utility GPU-Z by techpowerup shows the current mode. A screenshot taken with the app's built in screenshot button is fine.

 

[DaiBi]

 

[Harold]

But shadowplay works fine.

Means nothing because of how much back and forth OBS does between the video card and the main processor.

Have you tried using OBS Studio with the indistinguishable recording quality preset?

 

[DaiBi]

Thanks for advice. This is much better. Now amount of late frames is just 10%. But smoothness of recоrds is still very far from shadowplay. :( Guess i will use it then.

 

[Boildown]

Preset is on default. Change it to High Quality. Try it with 2 pass on and off to see which is better. And change the key interval to auto.

 

[DaiBi]

Preset is on default. Change it to High Quality. Try it with 2 pass on and off to see which is better. And change the key interval to auto.

Did it. And lagged frames are reduced to 1.5%. But still the difference between smoothness of obs and shadowplay is too obvious.

Thx for advice anyway.

 

[Boildown]

1.5% is still too high. You want that to be less than 1% for sure. Try High Performance preset if High Quality isn't fast enough. And post a log file from that attempt from a 5 minute or longer encode of high action gameplay.
