Question / Help Lag Spikes in the video

[Sio]

I have no problems at all recording a video with OBS, but when I look at the video it got lag spikes all over the place.

Here's a video of it: http://youtu.be/cxxNpdZWUSo
As you can see in the bottom right hand corner I have around 200 fps while recording.

OS: Windows 8.1 Pro
CPU: Intel Core i5 2500k 3,3GHz (Not overclocked)
GPU: Nvidia GeForce GTX 560Ti

Thanks in advance!

Does this happen when you output to file and view it in a media player as well? If so, please post a log file so I can see further details.

I use "File output only" and this happens when I view it in media player too. Where can I obtain the log file?

Ah okay, I see the problem. Try using 1.5 downscale in video settings or more, and it should solve the problem. You're just using too high of a resolution, and your computer can't really encode it very well (I should know because I have the same CPU)
