i tested this and using a free version(no expiry, full program) can really spped up my gaming exp and browsing exp..but if you can get a crack for this then its more speed bump you can get if you have 1mbps and up connection..try this..
ps: enjoying game is not all about cheats/hacks but a less lag the better and no lag is super.
