P: Stops detecting graphics processor after image resize

just had another thought on this. If the computer is a laptop, it would be sharing system RAM with video, which make available RAM for OS and applications even smaller

I defer to Andrew Sender, who is an Adobe person; I am a user... for what it is worth, I have 32 gigs of RAM in my PC and sometimes have to pause what I am doing and shut down all the many iterations of my browser (Chrome) to free up RAM. Things do get weird when I forget to do that periodically. You only have eight gigs installed.

My memory usage settings are:

Available RAM: 7422 MB
Ideal Range: 4082-5344 MB
Let Photoshop Use: 5195 MB (70%

That was the default on install and probably always has been since I've never changed it. I also have never had this problem and I've been using PS since Photoshop 6.

It's also probably useful to note that this problem doesn't happen if I resize using the "Fit To" presets. In other words, if I choose to resize a photo that starts at 4032 x 3024 pixels at 72 dpi by using the 8 x 10 at 300 dpi preset (which sizes it to 2400 x 1800 @ 300 dpi), there's no problem at all. PS still recognizes my graphics card and all is well. However, if I manually put in those numbers, I get the problem (screen flashes white for an instant, the photo resizes, but PS no longer recognizes the graphics card.) This behavior only began, incidentally, after the update before last. Historically, I've never had this problem and have been using this same machine for the last couple of years.

Should my memort settings be different than they are? Interested in your further thoughts.

Jim, et al: I may be misinterpreting what I see in the System information, but here's my observation. Installed RAM 8,130, Memory available to Photoshop 7,423 which is a little over 91% even though further down it says that 70% is allocated.  If it really IS 91% then your OS is probably having to swap to disc or some other function has to, and things crash...

Built-in memory: 8130 MB
Free memory: 5196 MB
Memory available to Photoshop: 7423 MB
Memory used by Photoshop: 70 %

I have exactly the same issue here. I have very powerful machine, but if I resize a little image (for exmple, from 200x200px to 1000x1000px) the GPU stops to work and the scrubby zoom or rotation stops to work and I have to restart PS

Hi Jim,
Can you please provide your Help -> System Info, for both before and after the image resizing?
