Microsoft Surface Pen lag in Photoshop

I have bought the Surface pen to use in Photoshop, however there is a severe lag when I use the tool. With some stroke it jumps around. It will start perfectly aligned to the tip, the the line will stop drawing as I am, then catch up again. I have tried disabling use of graphics processor in Photoshop, altering cache settings, uninstalling and re-installing driver, altering pen response time settings, etc. and nothing has worked. I have already spent about 5 hours between Microsoft assistance and a Surface rep trying to determine the issue and resolve the problem, but to no avail. I have also uninstalled and re-installed Photoshop to clear all settings that may have been altered. Nothing helps!
