djinn is right it is the OpenGL score thats causing the problem - however:
I too have just purchased a Macbook "SantaRosa" 2.2Ghz Black and was a little surprised to c the benchmark score for OpenGL so low. This test was performed using Xbench which I don't think is properly testing the X3100 shared graphics, given that the previous Intel GMA950 chipset is scoring higher on the OpenGL in Xbench - that can't be right as graphic and game performance is well documented to be up in performance with the new X1300 Chipset.
Unlikely:
If this were an OpenGL issue with the X3100 board in comparison to the GMA950 (going by Xbench results) then apple would be aware of it and probably would not consider this to be an issue for the MacBook Market. I find it hard to believe they would go backwards with this product.
Although a graphics update for 10.5.2 has been applied by Apple - don't know if this is an indication that their is an OpenGL issue with X3100 but it hasn't made a difference to the Xbench OpenGL test.
CineBench10 results are more accurate and here they are:
MacBook GMA950: 1260 (OpenGL Benchmark)
MacBook X3100: 2030 (OpenGL Benchmark)
A general note is that this macbook does perform very well with everything I have thrown at it so far. Its is also worth noting that GPU intensive apps are always going to an issue on shared graphics. I have not tested myself but from a gaming point of view I don't think its all bad
other users appear to have decent results with quality games - its worth looking at YouTube for video of both earlier and recent versions of the MacBook playing games like CounterStrikeSource and HalfLife 2 via BootCamp and CrossOver - see for yourself.
