They will have to wait till a release group or an individual releases a cracked patch 1.1 in order to use it one a pirated copy. Note that users with pirated or cracked versions of the game cannot install patch 1.1 normally (unless they are using emulation tools to emulate a leaked Clone DVD of the game). “Improvements made to general game performance” – This line alone should make you upgrade to patch 1.1 immediately.
I don’t know how it is for ATI graphics card owners but the game initially ran like crap even on relatively high end nVIDIA GPUs such as Geforce 8800. One major complaint about the game is that it’s extremely laggy and slow performance even on high end hardware which easily exceed recommended system requirements. Most of these are minor technical glitches but believe me these can be annoying. However the game is not perfect and has it’s share of problems. Recently released Spiderman : Web of Shadows seems to be a lot better game than it’s predecessors in many ways.
