Now, this is going to seem a bit odd to ask, but bare with me. Basically, I built my own gaming pc about a month ago and everything has been great. I tried to play an older game on my system and noticed it was really laggy. I thought maybe there was some kind of issue with my graphics card playing the game. I was playing the original Dungeon Siege and getting about 20-25 fps which is pretty poor performance for any pc nowadays. So, after looking for fixes and none of them working, I thought I'd try to switch to my APU (I have an AMD APU chip) to see if that somehow resolved the problem. I now noticed when I went to switch my primary display adapter that it was not an option and in the Device Manager it also was not present. So, my question is how might I switch to using my APU to play games and if anyone could explain why it's not showing up?
