I am not sure if anyone else is having the same issue. Whatever tool I use in the latest update of photoshop, it freezes, then lags and then sometime catches up. For example, I will start painting with a brush, it will freeze and then several seconds later it will not paint where I put the brush. It will just make a big blob. Another example is the transform tools, I will go to transform something, I will drag a corner to where I need, but then it will freeze, it will then finally catch up to where I moved the corner, or Photoshop will just crash. This same issue is with every tool I have tried. I have tried uninstalling and reinstalling photoshop and the wacom drivers. I ended up having to go back to Photoshop v19 to get rid of these issues.
