i don’t really know.
the input seems dampen. the global time seems ok (the animation is ok).
what is weird is that you say this happens on every project, and that seems like a template project.
also keyboard is kind of difficult to dampen.
you also say that it works well with other games. so maybe it is ue 5.3 issue. but i haven’t heard of this issue before.
do you have a build of your game or other game for a previous engine build?
or can you install, say, 5.1 2 4 or 5, and test that too?
