Helle everyone,

first of all: Please excuse my bad english, I am not a native speaker ;)

My problem is related to LOCAL RECORDING only. I do not want to stream!!!

Every minute OBS tells me that it took too long to decode and will skip frames. I do not understand that problem. I guess that my computer configuration is quite better than the ones of some people here saying that their setup runs perfectly.

If you have any hints, please let me know, I am truly desperate. I have read all the tutorials conceirning this problem, I have played with bitrates, etc.

And I think that 1080p@30fps with 8000 Bitrate should be no barrier for my setup.

Or do I need a new cpu? i7? If that is the case which one can you guys recommend? 4790?

My Config:

i5 4570
Gigabyte H87-HD3
8 GB RAM
GT 660

Thanks for your time and hints!

If it only happens every minute, there's probably something else on your system that is running every minute and taking up CPU time. Also you should check the local recording guide since your custom parameters are wrong.

Hey R1ch,

thank you very much for your answer.

I have read the guide and played with the options. It happens every time with every possible setting. It does'nt matter of I choose x264, Quick Sync or Nvidia. My CPU time is every time of the record below 50%, so I think there is enough potential.

What do you think about the CPU? Is it strong enought?

What else can I do?

Your CPU should be OK, but I guess it's struggling just a tiny amount. Maybe try downscaling to 1280x720.

Click to expand...

Downscaling did not solve the problem. Recording in 720p doesn't solve the issue.

So I think the problem has to do with my system config. I stopped virus scanner -> no change.

I have used all settings from the guide for 1080p and 720p with crf=20.

Any hints left?

I mean: Where is the problem? CPU time maximum on 50% :(

Another question: Any hint why Quick Sync does not solve the problem, either?

A friend of mine records with OBS on a laptop with medium setup and everything works fine :(
