Some week after buying new Macbook 3,1 with x3100 I started to see some strange things. I was comparing for my only satisfaction graphic results with my friend with macbook with gma 950 graphic card. And gues what... 950 appears to be a lot more efficient than x3100. It's all because openGL. When I was running xbench benchmark I scored: while my friend with 950 scored about 300 points in both. glxgears scores much less then 2000 fps Some games that I thought will run easily are just unplayable, like Heroes of might and magic. Some textures are just missing. Acceleration just isn't working for me. Any ideas why ?
