Camera Raw slower than Lightroom (latest versions)

[Fabio_Giu]

Hello to all,

    This is my problem: Lightroom works perfectly even with heavy adjustments. If I do the same adjustments on Camera Raw this gets slower. How is it possible? Do not they have the same "engine"?

Note:

   Camera Raw becomes slow when I use the adjusting brush (which is not even fluid if I use it first) or the graduated filters. Lightroom is always fluid!

I have a MacBook Pro late in 2016 - i7 2,7ghz - ati 455 - 512 SSD

Ps

I reinstalled Photoshop and Bridge, cleaned cash, upgrade cash to 20GB. The last is reset MacBook?!

Thank You All!

Fabio

You could try going to the Camera Raw preferences in Bridge and uncheck the option to use the graphics processor. That could make a difference.
