Hello all,I couldn't find any info about what the topic title says(or at least,I wasn't able to find anything).There is a simple question:with 3gb DDR2 RAM,would I see improved performance on a 64bit Win7 OS?Would I finally take advantages by using the LAA patch?At the moment,I run oblivion on win7 ultimate 32bit but I haven't installed the LAA patch because,as what I know,it works only on a 63bit system

No such thing as a 63 bit system. If you install the LAA patch you'll generally be able to run for longer without having a CTD in a heavily modded game, however it only really gets advantageous when you get to 64 bit RAM levels (4GB+). However it can't do any harm, so you might as well patch the executable, however you won't really see much of a difference.
