I have been using LR since the first beta, am quite comfortable with v.2, but am really having a heck of a time with v.3 Beta. Yes, I assume since it's beta it hasn't been fully optimized, but this just doesn't seem right:
Installed it on my MacBook Core Duo 2.4GHz, with 4GB RAM, made a small test catalog on an external FW800 drive, and I am finding it almost unusable - extremely long delays to update preview image, sometimes with every single adjustment in Develop module, the secondary screen (Loupe view) can take 20-30 seconds to update. And forget going to 1:1 view - the little "Loading" window sits there for literally minutes! - sometimes it never updates until I click out of 1:1 view, then click back to it. Makes it impossible to do basic things like compare the old & new rendering engines.
This is a tiny test catalog, about #70 images (Canon 5D MkII Raws), and running the "Generate 1:1 Previews" command makes no difference. LR v2 on the same setup is downright zippy - even with my main 10K-image catalog.
I haven't seen other reports of this - is it just me, or does everyone accept this non-performance as just part of a beta release? I do have "write metadata changes to XMP files automatically" checked - could this be a fatal error in the beta? Or is there something else I should be doing that I've overlooked?
Thoughts?
Thanks,
John
