ACR Lag Issues.

ACR (Beta) and 18.3.0.2528

Mac Studio M1. 128GB RAM. Tahoe 26.4.1

When loading images from Bridge into PS (Beta) to straighten uprights the guides are slow and laggy. Masks do not show coloured overlay and the whole thing is laggy.

This appears to have started from the last update.

If the images are opened into PS (Beta) and then opened in filter / acr there is an improvement thou when using the sharpening mask the mask isn't shown when the ‘option’ key is held.

Regards,

Mark

    Having the same issue with slow performance on camera raw 18.3, everything lags even zoom in zoom out, masks are incomplete or incorrectly drawing. Can't blame the computer as using M4 Max mac studio with 16 cpu, 40gpu and 128gb ram. Before it was flying with any edits until this update and I need to work so what should I do ​@adobe ?

    I am having same issue on my M1Max Macbook Pro. Pretty unusable! This is pretty unacceptable since my subscription plan has gone up to $70 dollars a month!
