Hi, I just got a brand new Mac Mini 2,26 Ghz Core 2 Duo, 2 gig RAM, and it's hooked up to my tv with a mini-DVI adapter. Snow Leopard installed. I noticed right away that the screen looks really sluggish, with screen tearing and laggy video performance. Playing videos in Plex for instance there is a lot of screen tear and I had to set the display to 720p to get it decent, and even then it's rough, even on SD videos! So I ran Xbench, and got a remarkable slow score on OpenGL; 43. My MacBook Pro running with the 9400M card got 97. Anyone know what could be causing this?
