Collision detection system discussion [Original title: Very low FPS]

I currently experience very low FPS when using OpenMW, like 20-30, however I do not have this problem whenrunning the game through the regular launcher. I currently have no mods installed. My laptop has an Intel HD Graphics 620 (integrated) with 16gb of RAM and an i7. Can someone please help me understand why I'm experiencing this?

Thanks

Moderator comment: This thread has gotten pretty off topic and is obviously no longer a support thread. There has been some important discussions going on in the thread however, so I changed the name and moved the thread. Sorry if there are any inconveniences. /Lysol

I should put that for comparison, playing with the regular engine with full draw distance i can get around 60 or higher. This is while just walking around Seyda Neen

Which version of the game are you using?

I know there were some recent performance improvements in the nightlies, you might try those. But running on integrated graphics is always going to be a bad idea. Yes, at this point OpenMW doesn't run as fast as Vanilla, but we'll get there.

It is hard to tell something without profiler output (F3 twice) and settings.cfg. Laptops often can not handle collisions detection well in OpenMW.

i think maybe i have the same problem too.. if i run openmw with integrated intel gpu, the fps is significantly lower than using the regular engine. However, openmw shows better performance when using dedicated gpu.

I thought, I had read that the nightlies were less performant, though that might have only applied to Ubuntu nightlies.

Interesting, what performance improvement did they implement? :)

Impressive that you are still confident about that. Especially since OpenMW depends on software made by other people which this project can't improve significantly. Are there still options to really get the basic physics about as light on performance as original Morrowind's?

Can you expand on that? Sounds like you've got some prior knowledge or had some prior discussion about this.

I meant Bullet and maybe also OSG.
There was a discussion about it, but it was more than a year ago and I can't find it. Something about physics problems and Bullet, I think.

GTA V uses bullet IIRC, so there's nothing wrong with bullet by itself. They say the documentation for bullet is horrible however, so the cause is more likely OpenMW's implementation of it.

That's what has been said about this before at least.

Thanks for clarifying.
