Hello lovely boys and girls.
I finally found a version of KotOR 2 that really works in my laptop, in my Intel Core Duo of 2.10 GHz with internal video memory of 256 mb. I have 4 gb of Ram, and believed or not I use Windows XP SP3.
KotOR 1 always have run very well in my laptop, but with KotOR 2 always got the infamous crash after the character creation. I really hate that
But, the Steam Edition works really well. I am witness of that, I have a copy of the Steam Edition, I'll really recommend.
