Guild Wars 2

Hey, the first time I played the game I had REALLY good fps, I could max out the settings and play flawlessly. However the next day I began having horrible fps, like 5-10fps which rendered the game unplayable, and now I have to have my settings at minimum to even be able to play the game. I have ran virus scans and deleted cookies to no avail. Here are my tech specs, should I be having these problems? And what can I do to fix them.

You should have a better FPS than that normally when you are in PvE by yourself. Lets check your GPU and CPU temperatures. If you don’t already have monitoring software that monitors your CPU and GPU temperatures, then I recommend grabbing HWMonitor, which can be found here:

Make sure you are looking at the temperatures after a few minutes of playing Guild Wars 2 so that the load has time to find a stable high temperature.

Make sure you are not limited by power saving settings.
