Question / Help Intel Quick Sync Problem

Hi guys!
So today I was trying out different gameplay capture methods and stumbled upon OBS and decided to give it a go. The Intel Quick Sync Technology looked really promising. I actually did a benchmark using it in "Shadow of Mordor" and it had absolutely no impact on the in-game framerate (of course, before that I enabled the iGPU Multi-Monitor option in my BIOS, I uninstalled the previous Intel graphics driver, which was already outdated, using DDU and then installed the latest one, tricked my system into believing that my Intel HD 4600 Graphics Adapter is connected to my display through VGA and so on). The problem is that the the video in the recordings runs for around 2 seconds, then freezes, while the audio playback goes on up until the end of the recording. I've already tried multiple configurations of the settings found in OBS but to no avail. Has anyone here ever encountered this issue? Any help would be appreciated.

Quicksync works with 1920x1200@60 on my PC, on a i5-3570k.
But Ungeheuer, you seem to have activated some advanced quality setting: LA_ICQ. This is the most GPU-stressing compression algorithm. Try ICQ instead, and if that doesn't work, CQP. I use CQP (it's the only available quality-based algorithm on my CPU), and that works with 60fps. The quality of the video isn't affected by this, only the size of the video. Or don't use any advanced Quicksync settings at all, use only the standard settings and boost your bitrate for some quality.

I recently upgraded to Windows 10 Pro 64-bit. I've already installed the latest Intel Integrated Graphics Drivers and the latest version of OBS. I tried all rate control methods and the only ones that kind of work are the CQP and ICQ ones (LA ICQ and LA (VBR) cause OBS to crash, while the rest cause the recording to freeze after the first couple of seconds and it doesn't unfreeze at all after that). The CQP and ICQ methods actually capture gameplay, though they cause the recording to freeze and then unfreeze over and over again, resulting in a stuttery mess. Any ideas how I can fix this?

On advanced options select quick sync preset balanced instead of best quality if you are going to record at 60 fps.

Thanks, that finally fixed the freezing, but there is one more issue - why does Quick Sync limit the in-game framerate to 60 FPS? Is there any way this can be undone?
