Hi, I on my laptop which is a Dell Inspiron 17 R 5721 there is a commutable graphics card. TheAMD Radeon HD 8300M and Intel HD Graphics 4000 . Recently I observed a large drop of the fps in League of Legends, thus making me updating the drivers. Afterwards it got worst and I cant seem to solve the recent fps problem nor installing the right driver. Even tho in the catalyst it seems to be ok, whenever I try to access Radeon Settings I get the "No AMD Driver is installed..." error. I tried a lot of things to fix it, yet the result would be mostly the same. And for the game, I dont have the uncapped 100 fps anymore, but a maximum of 40 fps which drops lower.
