Autoloading 8.25 Extended is jamming

I've noticed this myself when trying to shoot really fast but always put it down to my fingers locking up (I've got some finger issues).Maybe we're just reaching the fire cap and need to slow down slightly?

{EDIT} just update - I play on PC + attached dxdiag.

I know it is somewhat dated thread but this is EXACTLY what I am experiencing. I have recorded couple of gameplays so videos + extensive explanation below. Please advise  - this is insane, 80 % of my deaths with Autoloading extended is due to this. Videos below. 

The thing is that in very close combat, this gun "freezes", in some peculiar way. It is like a small lag, like if if the game skipped a frame or two. This tiny 0.1 second or something like that slowdown is enough for the enemy to finish me. I asked one guy in the game who played same gun extensively and he said he observed the same issue.  Does not always happen, but look at the videos I have recorded. Not always visible but you can clearly see there is some gap between the shots. 

The ping is perfect, 19-20 usually, I have reinstalled all graph drivers,  90-115 fps on a 144 hz monitor; good mouse, pad, etc . That doesn't seem to happen with other guns and for sure not those with fully automatic fire mode.

Have you ever noticed that for Autoloading 8.25 Extended?   Any thoughts?  Please take a look at the videos  - comments ones in bold and underlined are most strinking examples.

Seems noon really cares. Well, maybe one day then, thanks in advance.
