P: ACR 18.3 is unusable unless you disable GPU acceleration,

why do they have to break something whenever there is an update?????. 

I am also experiencing this issue with GPU on. Weoking on a Mac M3 Max with 128 GB of RAM, 

  Chipset Model: Apple M3 Max

  Type: GPU

  Bus: Built-In

  Total Number of Cores: 40

  Vendor: Apple (0x106b)

  Metal Support: Metal 4

  Displays:

Color LCD:

  Display Type: Built-in Liquid Retina XDR Display

  Resolution: 3456 x 2234 Retina

  Main Display: Yes

  Mirror: Off

  Online: Yes

  Automatically Adjust Brightness: No

  Connection Type: Internal

First of all camera RAW 18.3 is significantly slower, can't really use it anymore.

Second it totally freezes if you first change ratio/crop photo and after that want to apply a preset.

Is there a way i can downgrade back to the previous version?

Oh and this webpage to a form for bug reports is uselss! Because there isnt a form to fill in. (https://www.adobe.com/nl/products/wishform.html#sa_src=web-messaging)

I’ve consolidated the posts from the Announcement thread to this bug report and logged a ticket for the Camera Raw team to investigate. 

Thanks for making a separate report. 

It is definitely not the best to report suspected bugs on a product announcement and this is the better way to go. 

 

I'm having the same issue as a lot of people here the previous version of ACR I had no Issues 18.3 is barely useable unless I turn off GPU Acceleration, I'm using a 7950X, 5090, 64GB memory and NVME drives.

For what it is worth…

Oh, meant to ask - how can I vert to version 18.2? I can’t use this 18.3 and I need to get stuff done today.

I have this link to the ACR Plug-in Installer but it points to 18.3 or 14.5. I need to get to 18.2.

Hi. I just upgrade to version 18.3.0.2528 yesterday, and I immediately notice problems (prior version was 18.2.2.2512). I launch ACR from Bridge. When I fist launched 18.3 I noticed the fans in my PC and GPU kicked up and when I zoomed an image to 100% it was blurry. The same image viewed at 100% in Bridge is crisp sharp. And there is a little spinning circle in the lower right corner which I think means that ACR is busy. GPU and CPU activity is high. At one point ACR and Bridge were unresponsive and after 10minutes I had to kill the Br process.

Huge performance hit from the latest update. I’m barely able to work on my images as it keeps freezing all the time. I’ll need to find a way to downgrade because that’s frankly unusable right now.

Also not a fan of where the new Projection transformation is placed right now. That and the new Anamorphic setting pushed every other Geometry settings down. Now I need to relearn mouse placement as I mostly use Vertical, Horizontal and Rotate when working on photos. I need to work fast and I don’t want to keeps my eyes off the image when adjusting settings. But that’s mostly preference anyway

After the update ACR has a massive memory leak on the graphics card. When working on a picture in ACR the app gets slower after a few minutes and if you open the Windows Task Manager the memory on the graphics card (24Gb RTX 4090) is completely filled up and also some shared memory is used.

Please fix this as soon as possible!

Thank you.
