Question / Help What does it take for a PC system to have a frame perfect recording/streaming

[I3ordo]

before going into bed for a 60 fps dream, i would like to know what causes the OBS recordings to skips frames although having very low usage and no stats window errors.



is it a DMA engine that gives the video data to OBS? if then is there anyway to know if GPU is being maxed out on that? as current tools cant tell if the OBS is receiving the proper stack of image data from the GPU.

Normally , i would check the game, then gpu load, and cpu load and if they are all under 50%.



let me paint a picture.



cpu and gpu at 40% load, image is very fleunt, no stats window errors (like missed skipped frames) yet the fluid motion is disrupted when the change on screen is too much and too long



(game is super smooth)

Trouble Shooting:

Internet problems only

Stil having problems? Lower your bitrate
Stil having problems? Change twitch servers in your area
Stil having problems? Call your internet provider ( Its mostly them in my experience )

Hardware problems only
------------------------------------------------------------------------------------
Stil having problems? Play arround with preset usage
Stil having problems? Play arround with Process Priority
Stil having problems? Use NVENC H.264 Instead of x264 with similiar settings.
Stil having problems? Overclocking your CPU or GPU
Stil having problems? Try Simpel instead of Advanced in Output Mode

( There are no quality benefits to using a custom buffer size while streaming. )

Tips :

keep your CPU usage around 70%. ( or lower if possible )
Keep your GPU usage around 80%. ( or lower if possible )
