Those are sort of

scores from reputable places. Congrats to Massive for finally getting their breakout game.
Also, thanks to Blizzard for putting Vivendi so awash with cash from WoW that they gave Massive more time and manpower to make the game go from merely good to great.
Smooth-Regarding framerates, the game is really VRAM limited more than anything else when you turn everything up to full. Even a 768MB GTX-literally the card they had in mind when they were tuning the mode. The thing is that the combination of AA, AF, at the super-huge res you are running at 1920x1200-eventually causes you to just run out of VRAM. Also, Massive has said that while the game doesn't look as good, it does run better in DX9 mode rather than DirectX10 mode.
I don't think anyone is going to get 60fps at 1920x1200 on high settings for a good long while-I bet even the next revision of cards punt on it.
