Can I ask WHY??????
Would you want to run a 64bit machine at a slower rate at 32bit!!!
When it is designed to run as 64bit.
If you ever do any video editing trust me when I say use 64bit with 32 gigs of ram.
hehe it takes the poop out of 32 bit systems.
Allow me to give you an idea of the difference.
I compiled a video the other day with one of my mixes the file ended up being 42 mins and 14 secs long.
To render this into dvd form I used "ConvertXtoDVD 4"
With extra menus, total play time of 44 mins.
To turn this into a dvd in 64bit mode took me a total of 3mins 29secs
The same layout but on a 32bit OS took me a total of 12mins 2 secs
64bit mode setup
32 gig RAM
Nvidia 5800 quadro with 4 gig of RAM onboard
X2 6400+ AMD CPU
That's all the important stuff.
32bit mode setup
32 gig RAM (can only use 4gig in 32 mode)
Nvidia 5800 quadro with 4 gig (32os only sees 1gig of this ram) of RAM onboard
X2 6400+ AMD CPU
Now you can see why it helps in VT editing.
It does make a difference with all that ram.....
On a downside for me my graphics card is too powerful for BF2 and I get graphic issues when I have terrain set to high


but everything else runs just fine!!!!
