Question / Help [SOLVED] Always 18-22% frame drop on stream or recording regardless on application

[satishu]

Edit: As Harold is right: The issue is not droped frames. I described it wrongly in the topic and below.

Hi there,
i am new here and so i hope i will describe my problem well enough.

Currently i am streaming on Twitch or recording on a local harddrive. (Actually never doing both at the same time.)
For some time, i don't know how long, there is a huge frame drop on my system on every game and stuff i tried to record or stream.
Even the windows desktop has about 18-22% frame drops. The information i got from the statistics window.

I tried to set the fps to 48 instead of 60, but got also the same frame drops. Setting it to 80 fps gets the same result.
What i have done yet:
I cleaned the pc. Run a registry cleaner, harddrive cleaner, defragmentation.
I installed the most recent windows 10 updates, drivers for graphic card and reinstalled OBS studio to 21.1.2, recreating profile.
Edit: In the meantime i got the hint to use display driver uninstaller and reinstall the graphic card driver completely anew. Unfortunately it has not helped.

Although, i have set in my last stream the framerate to 80 fps. So i mostly got >60fps within this.
The log of this can be found at https://hastebin.com/fezixiroqa

However, Twitch connection has a quality of 100 and 12ms latency. Even if i run a local recording, i have same results as described above. So i guess, the issue is on something other.

So far i can tell my hardware was not loaded hugely. So my CPU was not over 50% load, also GPU and harddrive. Also my RAM was not maxed out.

As i have no further ideas and nothing worked, i humble ask for any help here. Maybe you guys can help me out.
Thanks in advance. If you require any more information, please let me know.

Your log is actually showing your frame problem is video card overload causing rendering lag, not dropped frames.

You have WAY too many game capture sources as well.

Thank you Harold for your review.
You are right. I did not read the issue right. I have to appologize.

I have reduced the game capture sources to a minimum and tried to monitor the performance of my GPU.

However, for me it looks OBS tells me quite still my graphic card is overload and drops 22% of frames.
I run a 20 second recording of "nothing", as i started the game capture source (Space Engineers) not.
Log file for this can be found on https://hastebin.com/naduzowusi

Also the graphic card looks not overheated or something. (The system was freshly booted after a night of shutdown.)

What can i do to decrease my issue more?

For first:
DVR - set to off
Antivirus - set to off
I see your resolution is 4K, it's litte high for capture, change to 1920x1080, fps change to 30, now you have 80fps (YT max. is 60).
I dont know about fps in game, but i suggest max 60.

After this, and 100% capture fps and etc., change to up fps, resolution and stop on best setting.

After turning off Windows DVR and making sure that Shadowplay or other capture softwares are not running, I would create a new scene collection with one scene, that contains of only one game_capture source. You can use one game capture source with auto detect for all games (despite some games, that only work with window capture).

Thank you guys,

I followed your advises and set Shadowplay to off (could be turned on due to reinstallation of drivers) and also set off antivirus and DVR.
Also i set the resolution to 1920x1080 and deleted all scenes and game_capture sources exept one auto-detect source.

After first test and capturing of windows desktop, my issue was gone. Although after reseting resolution back to 4K the resolution was gone.
I guess, the Windows DVR was the fault. Although i did not know such thing ever existed. Maybe it has activated with the last big Win10 update.

Short to all: Thank you guys, you helped me so much! I am happy now! :)

One addition: The issue is solved, but the cause was wrongly identified by me.
Previously i had identified Windows DVR as cause, but i can reproduce the issue without it.

Simply, i add a slideshow with looping images from a network source - directory or explicit files - to it.
Doing the same capture source from a local disc won't cause the issue.
