Playing PS2 isnt the end all be all for me... I own all versions of Vista in 32 and 64bits so its not like I do not have access to a 64bit OS, but I have a zillion of settings and programs I would have needed to transfer over to a new OS. 5min tweaking fix > Several hours of installing and re-configuring everything else just for one game. You dont need 32bit right now. There are only a few games in the future that will need 64bits, but PS2 isnt supposed to be one of them. There really isnt a good reason why I should upgrade to 64bit at this time instead of just waiting until I need to do the "transfer job" on my next computer anyway in 2013 at some point. That said the trick isnt silly. You increase ram for programs and decrease ram for Kernel. On a 4gigs system thats 3gigs access for programs and 800mb for Kernel (Total useable ram in 32bit is about 3,3gigs). My Kernel only uses about 250 of that anyway... A decent page file size on the side to enable the OS to offload everything of background stuff it can just makes sense to me overall. Regardless of PS2.
