You can't be sure if you are seeing it or not, unless you try the SAME hardware with Hardy and Intrepid. You will see night and day diference between them.
If you are using an overclocked CPU to some 3.1 Ghz it might be enough for Intrepid,(on 3ghz mine has some 20-25 fropped frames in the killa sample) but on Hardy a 2.6Ghz E7200 is enough for the killa sample. It is already some 20% performance difference.
An more and more i read about the new scheduler i get the impression that this is the problem. There are tons of threads about various issues with multithreading performance degradation with the new scheduler as it is optimized more on running multiple applications with even resource distribution than to have all the resources to one specific process. There are some parameters which can be tuned with it but it needs more research. I started a thread about this on kerneltrap.com forum.
