No, my system is Athlon64 3500+, my video card is ATI X850 Pro with 256MB RAM. It is more than enough to run any game on the market effectively.
However, this Pirate game runs exactly the same on my older computer, Athlon 900 Mhz, with GeForce4 Ti 128 MB.
As a programmer myself, I would have to say the programming for battle scene sucks. Whoever wrote this deserve to get fired. Why, because the battle scene cannot be more complex than the game itself, in fact, it should have less variables to keep track of, it should run faster than the game itself.
The game is very simple, unlike complicated games like SimCity, this is evidental, as the game runs fine on my old Athlon 900 Mhz. The battle scene is either slow by design (I don't understand why) or it is extremely buggy. Companies should test their games before releasing.
