Photoshop CC: Slow ALT key response for setting clone sampling area

While working with tools like stamp and healing brush in Photoshop CC I find that the responsiveness of the ALT key for sampling is very very slow compared to earlier versions like PS CS6. 

For retouching work it is imparative that there can be sampled and drawn consecutively very fast, which means I am sampling a different area often faster than a second. For some reason it takes Photoshop quite a long time to register the ALT command which leads to no new sampling area when it is done very fast. It often takes Photoshop longer than a second to register the use of the ALT key. For instance when I press the ALT key 10 times very fast it will only convert to the crosshair about 4 times.

Some people have already mentioned that it could have something to do with the multiple options the ALT key has, such as the shortcut for ALT Menu (a problem that goes back many years), and that this possibly might interfere with the use of the crosshair sampler. A workaround with thirdparty programs is not a route I want to take though, as I feel it is something that can be fixed by Adobe very easily if they were aware of the issue.

I am curious if other users also experience this lag or delay in the responsivness of the ALT key when sampling. And what might be a possible solution. However I feel it is an issue inside of Photoshop that came with the newer versions of Photoshop itself.

I'm having the exact same issue even though I have a really fast PC.

For me PS V19, V20 is slow, real slow. I was using V18, no problems and suddenly found myself with V20. Adobe Technical Support helped me back V20 out (it was  b r o k e n  ) and now V19 is what I have. I have bumped up my memory and given the scratch disk more space too (terabyte). That is the short story. PS is now running faster, but not what I was used to and many of my issues seem to be resolved. I cannot believe it was ALL me. I'm almost ready to post the rest of my story and maybe we all can post good news instead of bad. I know for a fact that Adobe reads the surveys and this page, so keep it coming. Good Luck!
