Emulator

im pretty sure this issue is in a few games but this is the easiest place
to see it. the intro to new super mario bros. the speed says 100%, vps says
60, but the fps says 30. now you may say that its supposed to be running at
30 here but no way. its running at half speed for sure. the audio also gets
incredibly out of sync at this part due to the slowness in video. in
earlier builds it ran way smoother and faster. i know this isnt a gameplay
issue but ive seen a few people complaining about an overall slowdown in
games and i think this may be related.

i do not have vsync on and i really dont think its a cpu issue, it sticks
to 30 fps the entire intro
