Speed problem with one game

Well I got this small problem the game runs normally at 2x speed but when I engage in a conversation (text) it goes back to normal speed. So when put FPS limiter on the game now runs normal speed but when engaged in text I get 2x slower speed. Can anyone help.

Thanks in advance.
(btw, the game is Dragon Warrior 7)
