This respectable system runs Crysis, Gears of War and all the other nifty DX10 games at high quality settings with excellent FPS, so I assume(d) everything is worked fine.
Then, I installed and tried playing good old Guild Wars, since above games are .. arguably .. pretty shallow in comparision

And I was in a for a shock!
On average, no matter which area, 15FPS! Changing the graphics settings - and this is important - made no difference at all. I had the exact same FPS with 800x600 lowest settings as I had with 1600x1200 highest settings, 4xFSAA etc..
However, I realized the fps drop is proportional to the view distance. When looking directly at a wall or at the ground, I get (still ridiculous) ~40-50fps. Once I look into the beautiful mountains they drop to 10 or lower.
On top of that, as soon as my FPS drop (e.g. as soon as I stop looking at a wall or ground) i get horrible interface lag. Keystrokes and Mouseclicks are registered with like 1 second delay. Not sure if that is normal in GuildWars or just me ...
Any ideas? Simple solutions probably won't help since I tried and asked ALOT already
