Unusual problem with laggy video.

[Meddi]

Hi, i just downloaded OBS and i have got a problem. On my video cursor is recorded properly (isn't lagging) but windows (programs) are refreshed every few seconds (on video you can see smoothly working cursor and usually cutted windows (only few parts of them are recorded) wich are refreshed every 3-7 seconds)). i have got very low cpu usage when recording (5-20%). What can i do? Audio is recorded well.
Im really soryy for my bad English :(
My specs:
Intel Core i5-2520M 2x2,5Ghz (4 Threads)
8GB of dual channel 1600Mhz ram
Windows 10
GT 610M

Thanks for help

1. Update your GeForce drivers.
2. Run OBS as Admin.
