Question / Help Framedrops in games - No idea what causes it

Hi OBS Community,

I have been using OBS for three years and never had issues like this.
As I am currently streaming Witcher 3 mainly, I have been running into the same issues from time to time, but not all the time, unsure what changed.

I am getting repeated little framedrops for a millisecond. I have checked CPU clock and temps, same for GPU, everything runs at full speed, as supposed. Tried different OBS settings, veryfast, superfast etc.
Taskmanager shows nothing unusual, my system is not completely at it's limit and I have not had these framedrops always. Two days ago I didn't have them, without any changes to my system.

Also, I tried streaming League of Legends with the same setup, 720p @ 30fps (Ingame full details, capped at 80 fps on WQHD resolution) and the frames kept dropping down to 30 fps on a regular basis, making it unplayable really.
Now even though my system is not high-end, I doubt it lacks the power to play and stream League, besides I could do it a few months ago, with the same system, could even stream Witcher 3 on highest settings, without these drops.


System is as follows:

i5 4460
16 GB RAM
RX 480 Sapphire Nitro+
6 Mbit Upload (steady)

The latest logfile: https://gist.github.com/anonymous/8f680da6c535ea4c5ee9bbd279b1dc73

What can I do to fix this? Any setting I have fucked up?

You mean the dreaded XBOX DVR thingy? Turned that off months ago, after CS:GO kept pestering me about it.
It's definitely off

Will try that, thanks.. been wondering about that anyway.. is it supposed to be used with only one game capture which has to be change or does everyone use several, unless a problem appears?


Edit: Deleted all other capture sources, except for the follower alerts, still the same framedrop issues.

Is there nothing helpful, any indication that can be taken from the log I posted?

Ok, so I seem to have located the issue.

As stated previously, the issue appeared in two games: Witcher 3 and League of Legends.
Both games were set to "borderless window" mode, while I tried to capture with Gamemode-source on OBS, which says something about captung a fullscreen application.
Now I have switched both games to fullscreen and no more issues with framedrops or anything.

So for anyone with similar issues, make sure you are capturing with right kind of source and make sure your game is set accordingly.

I haven't tested if window capture causes any issues, I am content for now with the results.
