The unit is milliseconds I guess.

Maybe check profiler output?

If you are reporting a performance issue, make sure to include a screenshot of Profiling output.

I've moved away from GLEW around the time core profile became a thing and GLEW didn't support it.

Nowadays there are scripts to generate GL loaders, so that you don't have to do it manually.

Well, the question is why should a function called Set take a non-const reference as argument? What is it setting?

Make it const Vector3& or pass by value.

Not sure if that is what you are looking for, but the bug tracker allows to query features. https://bugs.openmw.org/projects/openmw/issues?utf8=%E2%9C%93&set_filter=1&f%5B%5D=status_id&op%5Bstatus_id%5D=c&f%5B%5D=tracker_id&op%5Btracker_id%5D=%3D&v%5Btracker_id%5D%5B%5D=2&...

That's been known to cause people absolutely nightmarish headaches with mods whenever you fail to run with admin privileges with all sorts of games. In short, it breaks things left and right. It's actually almost certainly a greater headache for normal, non-programmer users with UAC enabled on Wind...

There is an environment variable OPENMW_PHYSICS_FPS which might be worth trying as a workaround.

Default is 60. You could try something lower and see if you still hit the spiral of death.

With OpenGL 4.3 you can use glMultiDrawArraysIndirect/glMultiDrawElementsIndirect to achieve what MajinCry is suggesting.

How much of a performance increase you'll get will of course depend on the driver implementation of it.

OpenGEX and collada are exchange formats. Afaik they are text based and very generic and thus slow to parse. gltf is a bit better, as it looks more like a text binary hybrid.

For performance you'll probably want something binary that does not require much, if any, parsing.
