Hi, I have a Dell Precision M4800 with 2 graphics, an ADM FirePro m5100 that is a dedicated one, and an integrated one that is the Intel HD Graphics 4600. The thing is that for some games I use the dedicated one (AMD) and for others I use the integrated (Intel) and that shows in performance. I have been researching and I have seen on the dell support page that there is an Exchangeable Graphics option. The thing is that I can't find it or the drivers. If you can help me.
