I just got crysis running on my 2.4 Sr 15". It runs like a charm without any driver downloads. Native res and all settings on high except shadows, some depth setting, and sound which are on medium. Fraps checks to a steady 20 to 35 fps except in cutscenes when the extra textures are loaded up. Then a lame 10 fps. No heat problems when playing crysis. I always prop up the back of the notebook when gaming to allow good airflow.
