Engine capped to 60 updates per second?

[Mudbill]

I know this question has been asked before, but all the threads I've seen don't seem to give a proper answer. I've pieced together what I believe is it, but if anyone knows or can help, please do.

I recently got a rig, including a 144Hz monitor. Amnesia (and Penumbra as well) does not display more than 60 FPS regardless, from what it seems. First off, it's limited to 60 FPS in the config, secondly it might be limited by V-Sync, but there's one more thing which actually is the issue here...

Even though I set LimitFPS="False" and Vsync="False" in the configs, the game will still not display more than 60. The debug FPS counter will tell me I have 200, but I can FEEL that it is not up to par with my 144Hz monitor.

I saw another line in the config, which says UpdatesPerSec="60.000000". I thought perhaps this one told the game that it would not GIVE any updates more frequently than this. I set it up but no noticeable difference.

So my question is, as you'll expect: How can I (if possible) achieve more than 60 visual frames per second in Amnesia (and Penumbra as well for that matter)? Is it limited because it will affect the engine physics at higher rates? Does the internal engine not send more updates to the view? I read in one thread that OpenGL does not support more than 60 FPS. Is this true?
