oh right, fair enough then I suppose. just a bit inconvenient if/when you have to do a full reinstall that you have to drag the whole pc out to get at the key to make a note of it.
Would have been more sensible to jot it down before putting the PC somewhere inaccessible? Where have you put it anyway? The sticker is normally just on the top corner on the side of a case, close to the front, just slide the PC out an inch or two and you'll be able to see it.
The new FF is a very demanding game, you need to play with the settings is all, you should be able to get a good trade between looks and performance with your rig.
