Question / Help Low fps game capture / High fps in game

OS: Windows 8.1
CPU: Intel(R) Core(TM) i7-4700MQ CPU @ 2.40GHz
GPU: Nvidia 755M SLI
RAM: 8 GB

I'm trying to record 60 fps gameplay with game capture, the recording is low fps no matter if I record it in 720p or 1080p, high or ultra settings in game, ect. In game my fps is 60 even if obs is recording, as if I am playing the game without it. The recordings turn out to be about 25 fps, all of them, at different settings.

I tried windowed mode and it works, I have to lower the in game settings a bit and set it to 720p or it gets a bit laggy but otherwise get about 60 fps 720p recording output.

So any ideas how to get it to work like that (get more than ~25 fps) in game capture too? It's better recording with game capture of course.

Any help?

Hi DTEnhanced, I am having the same issue. My PC isn't as good as yours but I can't understand why I go from 100+ fps (Not streaming) down to around 20 fps (Streaming to twitch). If I find anything out I will reply back to this post.

george passmore · Jan 18, 2015

the problem is obs is taking more cpu off your game then you'd like
id suggest assigning cores and only stream at 30 fps as 60 fps on twitch isnt needed
goto task manager and right click the game and obs and click set affinity
obs will proabably need atleast 2 cores

Thank you I will also try this!

Thanks for the replies.

But like I said I'm having 60 fps in game but the recorded file is low fps, I just can't get game capture to try and do the recording smoothly, obs' priority is already set to above average. Looks like my problem is opposite of yours Ender51. :p

Yes it is. Maybe try allocating cores to certain programs e.g 2 to OBS
