I haven't tried logging in yet to see if there actually are any issues, but I did look into the drivers.
I am currently on a laptop that uses Intel HD graphics (not ideal, I know, but it runs WoW pretty well). I checked the Intel website, but it won't let me install the updated drivers from there, saying something about "custom" drivers. I went to Toshiba's website, and they don't have any updated graphics drivers for my computer.
So... is there a workaround for this, and what kind of issues might I encounter with pseudo out-of-date drivers?
