Things going invisible

In a lot of my matches  things start going invisible in my vision, my hands and the items i'm holding dissapear, my weapon disappears and when i'm aiming i have to guess where my shots are gonna go, loot is invisible on the ground, enemy models are all glitchy.
If I was playing casuals I wouldn't mind too much, but I'm playing ranked and it is really, really, REALLY frustating losing RP beacuse of a bug like this, for example my last match, I was trying to kill a Conduit with a spitfire, first her model was all weird, and second my Spitfire wasn't appearing on my hand. I already tried verifying the integrity of the files but it continues happening.

If this could get fixed I would appreciate it a lot. 

Thanks.
