Question / Help Trouble recording DOTA 2

[arteh]

Hello guys,
Thank a lot for this awesome program, it's really easy and I'm making it my default.

However, I have stumbled upon a problem when I try to record the game DOTA 2.

1. I open OBS as admin
   
2. add a source: game caputre
   
3. open dota 2
   
4. go alt tab and choose dota 2 as application for game capture

Now, when I start recording, the preview shows that the game is being recorded but it's choppy/laggy/frame dopping.
HOWEVER
as soon as I go in to the actual game,
move camera etc,
then i go back to windows,
stop the recording
and when I watch the recorded video, it seems that it only recorded while i was out of the game i.e alt tabbed
What's happening?

Nevermind, it appears that my 5 year old phenom isn't able to record smoothly in 1080p. Downscaling to 720p seems to do the trick. It still have stutters/choppiness but I'm experimenting with settings and the inital problem is solved.
