64 bit vs 32 bit (not dual core)

[Shiverwarp]

How much increase in performance would I get going from 32 to 64 bit but not dual core?

At this moment there is a huge performance difference between 32 and 64bit! But that doesnt only result of the 64bit feature which means that a future 32bit release might also get fast speeds...

I'd say an average of 10-15 FPS, some games more. They are working on a new 32 bit build and I see no reason it cannot be as good as a 64 bit version with a lot of hard work.
