Question / Help OBS lag?

[Chizbang]

Hey!
I have been using OBS for recording locally (using it for Youtube videos) on my Macbook Pro 2012 with a 650m for a year and its been running beautifully on everything...

I have just got a new gaming rig to accopmany my macbook. IT has the following specs:

i7 2600k
PNY GTX 570 1.3GB of video ram
12 GB of DDR3 ram
Windows 7 x64 ultimate

I have noticed, while recording my Gmod seassions which are usually very smooth on my laptop (with the 650m in it) its pretty laggy. Im constantly dropping below 30 where as on my mbp its a really small drop (it never ever goes below 50 at worst). Any ideas as to what can cause it? I know Kepler GPUs have a h264 encoder in them making it easier for recording, does OBS utilize this feature?

Heres my logs:~

Im not using V Sync in game and the game runs fine while not recording.

20:37:51: fps: 80
20:37:51: width: 1920, height: 1080

a bit of a heavy load depending on what game you try to record


since you record stuff for youtube you could just record it with 1080p30 since youtube reencodes it with 30 fps anyway

Yeah, I tried 30 but it didnt help. Think I should be doing 720 for optimal performance? Garrys mod is the game by the way

no 1080p30 shouldnt be a problem at all on an i7 2600k.

so i still wonder what game you try to record.


*well you just edited your post ... but still garrys mod shouldnt be any problem at all.

maybe try enabling aero and use game capture only since you try to record ingame footage only
