Ty the tasmanian tiger 2 lags, but the first game and third game don't

[xlegendxla]

I recently downloaded the latest version of dolphin emulator, and I wanted to play Ty the Tasmanian Tiger 2. I played the first one just fine, but as soon as I get into gameplay of the second game the fps drops significantly.
