Figured out what's causing games to run very choppy like. It's when I connect my Bluetooth controller. It plays fine when I don't have my Bluetooth controller connected when I connect the controller the game is very choppy.

version r6. I'm useing sonic adventure 2 as an example. at first it played perfectly, now all my roms play choppy and skippy. the game plays very studdery. i dont remember changing any settings. could there be any reason for this sudden choppy emulation?
