El Capitan's Finder is very slow with large images

[pier]

For RAW files I've been using this app that was on Nikon Rumors. It's basically a plugin. The RAW files show instantly when I click on them. Massive time saver and I don't even want to remember my job before it. I've been using it with Yosemite and hesitating to install El Capitan in case it goes back.

Did you finally try Raw Right Away on 10.11?

Yep, Finder is painfully slow. I had to Bootcamp Windows on wife's late 2013 15" rMBP because she was frustrated how slow Finder is opening her RAW images. Unacceptable.

I'm the app developer. Please forgive my lateness answering. I only just noticed this thread.

Raw Right Away is fully compatible with OS X 10.11.
