Guild Wars 2

Now I fixed it. I don’t have hybrid graphics, but the AMD video card was refusing to get out of power saving state when playing GW2 unlike other games which are working fine.

Untill last patch I was running the game at 60FPS on mid-high settings, today I can’t get more than 16-22 FPS regardless if I run it on ultra high or low settings.
I did restore my windows partition to a previous working backup just to be 100% sure there is nothing wrong with my PC. I have 3 PC’s running intel video, nvidia and AMD. The fps drop only happens on the PC with AMD videocard and I don’t think is a CPU (FX8350) bottleneck.
All other games are working fine except GW2.

I want to buy a new gw2 key for my husband. I found a cheap key for only 40 euro on CJS and Offgamers. Can i buy it from them, are the keys legit?

Every time gw2 receives an expansion, is it free, or do i have to purchase it?
- If is not free, then what is the cost of expansion?
-How often(per year) will the game be updated with paid expansions?

Thank you,
