I run maximum settings windowed 1920x1200 and load in less than 35 seconds every single time...
no idea why RogueBagel is so slow with such similar specs as me (see below);

win7 64-bit
Quad core, q9450 2.66GHz
4 gig of Ram
Galaxy GTX 560 TI 1gb card

My "windows experience ratings are:
7.2 for mem/proc
7.8 for gaming/graphics
5.7 for disc transfer rate

I've also got the fastest internet available in my area- 10mb or something.
What kind of internet connection do you slower loading guys have?
