yeah its a big download, but once you have it then thats it.
Its pretty cool aswell as once you have run it you can see online how your pc compares to other similar setups and also what your ranking is against everyone whos ever ran it
ya... its a big download.. also don't be alarmed by the FPS that your PC gets when the tests run... even for the 3dmark06 world record holders the FPS during the tests are pretty low....
