Okay, so I've tried playing Titanfall over the past day, and for some reason I'm getting the stretching textures and invisible gun again. This strikes me as odd, as it was working properly as recently as last Monday (that would be two days ago as of the time of this post, on March 17th).
So on a hunch, I went to check the driver version, and for some reason the driver reverted to its previous state, before the beta driver. While I attempt to reinstall the beta driver, can anyone come up with an explanation as to why the driver would revert to its pre-beta state without my telling it to?
