yes it's depend on the time you down load it.
the first time it was around 50kB/sec (corrupt copy)
the second time it was around 320KB/sec
with just 4 houre in between
but the controls are a bit on the slow side, with the mouse pointer , you have to "touch" the border of you screen, but because i have a wide screen, it takes ages to reach the other side.
and after playing 5 minites a got a "sick" feeling and had to stop playing.
