Action delay issue

[power8888power]

There seems to be some coding problem screw the action execution order in this game engine, some actions delay 0.5~1 second before execute when in combat with enemies, including using pip boy, switching weapons, fire, melee....etc, not stutter or lag issue because game runs perfectly 60 FPS with my GTX970, nor mods problem. Specially when trying to burst fire in auto weapon, it's really a pain in the ass. Switching weapon take even more seconds in combat, making quick draw a joke. Anyone feel the same or just me?

Some of those delays are deliberate. You can't, for example, instantly switch between weapons.
