i have an inspiron 15r 7520 and i want to update my amd catalyst drivers, cuz i'm still on 12.03, which is about 2 years old.....
i want it because the mantle thingy looks much of an advantage to my laptop, but there is no that driver support for amd catalyst controller, so.......
how? i tried to install the drivers that i downloaded from the amd website, but it doesn't work, the laptop thought i had no graphics card....
