I am playing a processor intensive game, arma2 dayz, and would like to assign more ram to my graphics display which is built into the mb. I run a i5 core with 6gb ram and windows 10. How can i boost graphics performance without buying a card. I have a minitower and 200w power so getting a card is not feasible. Also, my ingame fps is fair, around 35 to 40, but i experience crashes from time to time and i know server location is also an issue.
