Guild Wars 2!

[Shadow]

To be fair, the build used for the bwes is unoptimized and cpu heavy. There was also a lot of lag from the number of players, especially on the fridays of the bwes and in the low level zones where everyone was.

The build for BWE1 was unoptimized. BWE2 was quite a bit better.
But even if it hadn't been, that doesn't explain why I was lagged out in the level 15-25 zones when there were only about twenty people fighting in a world event, nor why no one else in my party/guild was having these issues.
The more people that are around the worse it was. That's to be expected.

I'm merely pointing out that the wonderful tool linked to help determine if it will run said that I passed with flying colors, and that I was having many issues while others on better systems were not.
It won't be a problem for the final BWE as I'll have an i5 2500k and 12gb of RAM. Basically I'm building a system that was top of the line a year ago.
