Seriously, it's not the flaw of the game, but the limitations of the machine with which you use to play it.
^^^ This is the exact reason. However, I agree with you thata poor draw distance with tons of pop-ups,
is a really nasty immersion killer. Especially when you have half a fortress popping up from nowhere 30
yards ahead of you. There are some excellent mods out for the PC to remedy this, but they come with
a somewhat hefty performance hit. I was not able to run them back when they first came out, or my
game would come to snails pace fps-wise. Today I can run them with no major hit and to be able to
stand up just south of Bruma on a sunny day, look out between the trees, and see every ruin/fort etc.
all the way to the horizon is a sight to behold.
