I started playing roughly 4 days ago and i've been getting this I would believe texture glitch and it's been getting worse and worse everytime I log in "it's only for this game" I'll post some screen shots of what my computer is and what is going on I can't find anything to fix this and yes I updated my drivers and whats currently happening is still just as bad before they got updated

When I first start up the game everything is fine but once someone uses a skill or a animation it bugs out and makes a strip of w/e that is and just gets progressively worse I've redownloaded the game twice and like i said upgrade my drivers, i've tested other games if my 660 gtx ti is bad but they are working perfectly fine. this is ruining the game experiance for me and I really do enjoy tanking if there is anyway this can get fixed I would really appreciated it thank you very much
