i think that you need a better cpu for that resolution. (Video -Custom = 1366x768)
Try a bit lower, like 960X540 or lower.

I think that it could be the problem, check it anyway.

And try to change x264 CPU Preset lower than Ultrafast, to faster or lower.

He was already at the fastest x264 preset (Ultra Fast). Try bumping the quality setting down; you have it at 10 currently. Also try bumping the bitrate down. Your CPU is not the greatest, and you are also using Intel integrated graphics. You might be asking too much of this system, I'm afraid to say.

I know he was at the fastest x264 preset, and thats the problem with that cpu.
He needs a lower speed option as; veryfast > faster > fast > medium > slow.
Higher than veryfast or faster, you will need a newer gen cpu i7.

.. and yes, try bumping the quality setting down to 5-6, and a lower bitrate.
