it helped alot.. down to 400ms... not the greatest but still ok i guess.. some lag between clients even though on the same machine.
This most likely has nothing to do with Keyclone. It's the amount of time it takes for information to get to the WoW server and back to you. There will always be "some lag between clients" because they are not directly communicating, the other client has to get information from the server in order to show where you just moved, for example. Actually, I find it pretty creepy when latency is extremely low, because everyone stays so close to the one I'm playing, and sometimes it makes me think I have broadcasting enabled instead of having them auto-follow. I seriously doubt that Keyclone is the difference between a 400ms and 1100ms ping. It's more likely to be caused by your neighbor downloading too much porn (or the torrents or trojans running on your PC).
As for my equipment.. 64bit came with the system or i'd be going 32bit honestly.... the vid is a new 9800GTS nVidia 1gig
64-bit support is pretty good these days, and it still runs 32-bit applications (WoW, etc) anyway. Any new PC that is capable of 64-bit should probably have a 64-bit operating system. You wouldn't want to downgrade to 16-bit, after all, why 32?
