[jacky400]

I'm running multiple time of a Wii game (Arc rise Fantasia) using Dolphin v4089, however , i discovered one thing that FPS sometimes is higher and next time i open it again , it back to normal standard FPS . Anybody seen similar thing like this ? i attached two game screenshots .


First one is 28 FPS while second one is 23 FPS .Both are taken from same machine .
