Recently openmw master gained support for async physiscs, see https://forum.openmw.org/viewtopic.php?f=8&t=7148 for some background info.
To use this you need bullet with multihreaded support. Repo package doesn't provide that.
Use my new aur package https://aur.archlinux.org/pkgbase/bullet-multithreaded/ and rebuild openmw-git against it.

openmw-git has been found to require a sizable amount of temporary space during building.
The available amount depends on system specifics so is different for all systems. In case build fails with "no space left on device" you may be bitten by this.
See https://bbs.archlinux.org/viewtopic.php?id=277304 for details and possible solutions.

Please refrain from flagging the git version as out date when a new release comes out. The git aur packages update their version on install time based on the tags of the git repo.
Keep in mind that this is a VCS package and it is meant to be in line with the latest master which might not always work. It is not meant to follow the release pattern in any particularly smart way and assumes that upstream maintains their tags consistently.
For the newest release, the correct page is https://www.archlinux.org/packages/?q=openmw
