New patch issue

After the patch was installed the other day, I started the game and a pop-up window said my graphics card drivers needed to be updated. I had just done so a few days earlier, so I closed the window and logged in. The game was unplayable with nearly everything not getting rendered, showing just a gray screen with objects trying to show up but glitching madly, yet all of the UI worked fine. I decided to update the drivers, but I got a notification that they were up to date with the latest drivers. I tried reverting to the previous version of the drivers and that made it worse. I'm hoping it's just a bug, but my PC barely meets requirements to run the game, and it ran fine before the patch, as I kept it in queue and played for an hour before going ahead with the install. Is there a way to roll back the patch until this gets fixed? More like in case it doesn't get fixed, since I already contacted customer support and they pretty much said they're not doing a damn thing about it.
