Guild Wars 2

Hi all,
I just wanted to post with my issue, I played through the betas on max settings with no lag or FPS drop at a steady and good FPS rate, since the second last stress test when the game underwent more optimisation, I started to get significantly lower FPS and more lag.
Its so bad that I’ve barely been able to play since launch, I tried again today and my FPS was at 4, so I’m wondering is this because its got so much more demanding since beta or what and is there anything I can do?

System Specs:
Processor: Intel® Core™ i3 CPU M 330 @2.13GHZ (4 CPUs), ~2.1GHz
Memory: 4096MB RAM
DirectX 11

ATI Mobility Radeon HD 5400 Series
Memory: 2736

Thanks in advance!

Hi,
I’ve been disconnecting constantly, I can’t play 5-10 minutes without crashing, if I am playing longer its with extreme lag, this makes it impossible to do story missions or even really just play!
I didn’t have any problems with this in the stress tests or beta weekends, the first weekend of launch was fine too.
Just wondering if anyone else had these problems or some advice?
Thanks
