In this particular situation I wanted to tell you that I have installed Trine 2 Beta on the computer. I was able to run the game at the resolution of 1920x1080 which is having Very High Graphics. I have also applied for the 4x Anistropic Filtering as well as Triple Buffering and the game is supposed to running smooth. But after installing full version of Trine 2, I have played the game with the same settings and it supposed to sluggish while playing. Let me know if you are having any speculation on this particular matter.
