Pen pressure stops sometimes

[Piratefoxbox]

My issue is that I run windows 10 with photoshop CS6 with the latest Wacom driver on my cintiq
sometimes however, my pen pressure is gone on some strokes, this is really hard especially when trying to do line draw or specific areas as suddenly every brush feels like on its 4th stroke will only have one setting.

things i tried:
disable/enable windows ink
disable flicks
disable double click
disable anything in the world basically
reinstall wacom drivers
cleaning the tablet and the pen tip
other thing i probably forgot
.
Im going nuts over this :/

Was your tablet or pen tested? Maybe it's broken? Other than that try installing it on another computer and see if it works properly. If it doesn't, it means something might be wrong with the tablet.

Often enough it seems to be a problem with either several drivers being installed, or antivirus programs messing with the installation. Try uninstalling all drivers and doing a clean reinstall while your antivirus is disabled, and create an exception for the folder containing them.
