I have the new i7 MPB 15 inch with the HD screen, and lately I cannot play any flash fullscreen without the video stuttering. The only way to fix this is to manually turn off the intel graphics in the energy control panel. The video plays fine with the nvidia graphics, but burns through battery like crazy. Has anyone else run into this? I could swear the problem started when I installed the 10.1 flash, but im not exactly sure. Maybe this version enables the intel graphics while before it was using the nvidia automatically? Either way I would assume the intel graphics can at least handle flash video playback, kinda annoying if I have to use nvidia graphics all the time.
