images in photoshop appearing pixelated

I'm using a Mac Pro (2013) OS X Yosemite Version 10.10.5 and photoshop CC 2015 with all latest software updates. I have noticed that photographs opened in photoshop CC appear pixelated and over sharpened even when opened from RAW files that have had no editing applied. I had previously been told to turn off the graphics processor in an attempt to deal with Photoshop CC no longer zooming correctly. Could this be behind the pixelation? And do I really have to choose between an ability to zoom or an ability to have a clean sharp image in front of me?

A fix for what, exactly? This is handled by the OpenGL engine in the video card driver.

The only way to see the file accurately is to map one image pixel to one screen pixel. That's what 100% means.

Any smaller zoom ratio, and you have to let one screen pixel represent arbitrarily more than one image pixel. Obviously this means some zoom ratios work better than others - but how that fractional resampling is done, is determined by the driver.

Oh come on.. Nobody of you guys didn't remember to just reset the whole photoshop? That is the easiest solution to this problem, I just did it in less then 1 min.. CTRL + K and press Reset Preferences On Quit. Reload PS and that's it. Can't believe no one wrote that in 5 years.

No-one wrote that because it is not a fix for the GPU driver issues raised by the poster 7 years ago. Resetting preferences resolves many issues but does not update a GPU driver

The issue is not GPU driver, it's just some PS bug. I was editing pics normally 2 days ago and this bug happened today. Exactly the same problems as author's. Random bugs can happen from time to time or some accidental clicks. Driver issues are mega rare.. Simplicity is the key sometimes. People need to know that.

This worked for me by simply updating the device driver

Same issue with a PC, open to 100% no issue in Photoshop, anything smaller looks Pixelated. Adobe surely has a fix?

Mac has now dropped OpenGL for Metal... same mess | different drivers

i.e, nothing to do with Adobe guys

That's the power of marketing for you

Seriously, all Adobe applications work exactly the same on both platforms. Each platform has its own problems and technical solutions that are less than optimal. Don't believe the ads.

Hi GerenArgyII,

When you open the image in the camera raw does the image looks pixelated. Is it happening with only specific image or all the images.

Thanks

Hi,

Images all look fine in Camera Raw - pixelation only appears once they are opened in photoshop CC. As far as I can tell it's all images but not all zoom levels. So if I zoom in or out, sometimes it sharpens up nicely, other times not. I tried turning on the Graphics processor again but now it won't open images properly at all - just glitched blocks and blank bits..
