Query: Pity

Very nice game. Super Idea. Great graphics. More than I could imagine about a PC game, until I started to play it. Unfortunately sometime after you install you'll face some problems of performance. After playing for 2 or 3 rounds it became very hard to play, slowing down considerably, becoming choppy, answering with delay to every command. A pity.
