Dual screens on G46vw not working like my G74

[City_Builder]

Hi,

I have hooked up an external monitor to my G46 and I usually play live streams from twitch.tv on the laptops monitor while playing a game on my external monitor. On my G74 this works perfectly, however on my G46 which supposedly has a better GPU the twitch stream on the laptop monitor slows down to about 3 frames per second, (the game plays fine however), on my G74 both the game and the live stream work perfectly and are completely fluid.

Any clues what might be causing this?
