Don't need a new video card
At least not an AMD one. The max load I saw while playing Battlefield 1 was 57%, and it was using 2.4 GB of VRAM.
A new video card probably won’t fix the big FPS drop that causes stuttering. Don’t know what the load is when it drops. The AMD overlay doesn’t work, click ALT R, and nothing happens. You have to go into Task Manager to see, leave it open, and use ALT TAB. You’ll only have a second to see the load, it goes down when the game is minimized.
The AMD driver could be the problem, nothing I can do about that.
