Speed up Lightroom 2.0

One of the touted benefits to the latest Lightroom upgrade is the 64 bit support. So, why is Lightroom 2.0 running so damn slow? After some searching various message boards I found the reason. Lightroom 2.0 defaults to running in 32 bit mode. Just change it to run in 64 bit mode… right?

And here’s how:


Uncheck the “open in 32 bit mode” box and then start.

Seems like funny place to put it… right?

    Cool, I’ll give this a try. Thanks.

    I wonder if it defaults to 32 Bit for everyone, or is the installer smart enough to look at the computers specs and make a decision during installation?

    Just installed Lightroom 2.5. My “Get Info” box doesn’t have an “Open in 32 Bit Mode” box at all, just “Locked” (unticked)- is it already running on 64 bit? How can I check? -Thanks!
