Hey everyone, as the title implies I am playing Guild Wars 2 on Ubuntu 12.10 (recently upgraded from 12.04.1 LTS) and the gameplay is awfully laggy, as in 8-10 fps in areas with little activity, and then it drops to as low as 2-3 fps in areas with a lot of activity. The gameplay was also the same in Ubuntu 12.04.1.

A couple tech specs of my machine:
Processor: Intel Pentium D 2.66 GHz dual core
Graphics Card: nVidia GeForce 550 Ti

I am using PlayOnLinux to run the game, and so far.. it had gotten the job done, but not well enough.
Basically what I'm asking if there is something that I need to do in order to have the game run smoother, or if it just my piece of junk processor. I am beginning to think that it is my processor since I am tried multiple combinations of methods..

Any tips?

Thanks,
Nanur
