My GTX260's Shader Model 2.0 Scores

Is this normal?

I replaced my 7800GT SLI with a single GTX260. However, shader model 2.0 scores in future mark have hardly changed, but the SM 3.0 scores show a much greater improvement.

So older games don't really show that much improvement, but FEAR 2 runs happily at 50FPS on max settings, isn't that a bit strange?
