@chill1184 I agree with @ragnarok013 if the card / part was dying it would effect all games. Try this for settings in BF1 once your in the load out. I play with video settings all the time as I am a Frams per second crazy person. You fully need more ram in your PC for BF1 as recommended is 16GB and you have 8GB but for now try this for in game settings in the loadout before you try and go into a game.. I don't know AMD cards at all but look in catalyst control center on your desktop and see if it has some type of setting to set the PC video card to to performance if it does set the PC video card to performance.
In catalyst control center look under gaming tab and performance etc anything to set it to performance over eye candy. As eye candy is useless when it comes to PC performance lol.
In game video settings Advanced right side set to custom and set everything to low for testing but turn off ....
1-antialiasing post off
2-ambient occlusion off
Also make sure GPU memory restriction is OFF
EDIT>>>> Will the game load out even load for you ?
See if this will help get you into game :]
