And last I checked, there is no \"castle.\" I guess you mean the Laanx Temple? Hydlaa Plaza has a lot of polys to process, so it\'s one of the more graphically intensive areas in the game. If you were to go to say...the sewers it wouldn\'t be nearly as bad.

There are some ways to reduce the amount of work your graphics card must do while playing the game. Please use the forum \"Search\" feature in the future because there have been
many threads regarding this exact problem. Unfortunately, the problem is frequently with the hardware of the user\'s system and not the game itself.
