I have gathered all the requirements for my computer which are necessary playing Dragon age 2. I have a Direct X11 in my computer and the computer has been configured very well again. After that I have installed the Game. After completion I have launched the game. It loaded well without any delay. As game begins I realized that there is much lagging and the graphics also not very well. After 2 to 3 minutes the game crashed and I couldnít able to do anything. It just closed by itself. Why?
