Since the newest update photshop freezes on many occasions. I have often problems which seem to depend on the GPU. In older version I could deactivate the gpu but in the newest version this seems not to be possible as you can see in the picture below.
My GPU is an old intel HD Graphics 4000 on my notebook but in the previous version of photoshop it was recognized correctly and everything works fine for me. The driver was updated to the newest version.
