*Updated for patch 4.3.4*
A 64-bit client is once again available for use with Patch 4.3.4. Before being able to launch WoW in 64-bit mode you will need to download the 64-bit client for PC/Mac (using one of the links below), and unzip it into your World of Warcraft directory. Once you extract the files you can start the 64-bit client by opening the Launcher as normal (Run as Administrator if applicable). To switch back to the 32-bit client, go into Options -> Game Preferences, and check the Launch 32-bit client setting. The game will display which version you are using at the bottom left hand corner of the login screen. ex: Version 4.3.4 (15595) (Release x64)

As I mentioned in the last thread, I've seen definite improvements on this system. 4 GB RAM + 1 GB Video RAM.
I can run ultra in Stormwind flying around at 24-30 fps, which was not possible before.
The biggest improvement to a single setting seems to be shadows.
It's popping over 100 fps in some locations at my usual settings, which has just never happened.
Load times are improved.
I even ran both clients simultaneously on the same machine (just to mess around/test) and lifegripped my DK all over SW, with no problems at all.
I only need to fix my resolution when I switch between the two clients. I use the launcher and it seems to remember the resolution as long as I don't switch back to the 32-bit client. Still, it probably shouldn't mess with that setting when you switch clients.
@Justicar: If you did not have the 64-bit client you would have no option at all to uncheck the "launch 32-bit client" option. So go ahead and leave it unchecked and log in, it means you have and will be using the 64-bit client.

Hi, my video settings seem to be reseting to low when I launch the game. I'd rather not have to manually reset them every time.
I fixed it, I had to apply the administrator option to the wow-64 application along with the launcher.
