Pulse Rifle damage bug

The Pulse Rifle has been widely reported to be quite poor in the Dead Space remake and it turns out it's due to a bug related to how its damage is applied.

According to this Reddit Post which quotes this Korean forum post, the Pulse Rifle's issue is that enemies apparently have a 0.2s invulnerability window upon getting hit. This results in the Pulse Rifle wasting huge amounts of ammo and DPS when fired full auto, particularly with the rate of fire upgrade. There are even comparison videos comparing automatic fire and an autoclicker which tap fires at 0.2s intervals. With the autoclicker the DPS is noticeably better. I can also verify from personal experience that removing the rate of fire upgrade made the weapon much better for me.

I'm aware the game hasn't been updated in a while but it would be nice if the rate of fire was adjusted to at least max out at one shot every 0.2s and the damage numbers tweaked accordingly, assuming the core bug is too difficult to fix (even though it also effects the Plasma Cutter apparently although much harder to achieve due to the nature of the weapon).

It's also important to note this bug in case of any future installments based on the same engine as high rate of fire weapons are also present in the sequels (especially Dead Space 3), or maybe even other Frostbite Engine titles.

Hope this post proves useful to someone.
