Pressure sensitivity responding more to speed than actual pressure

[Prof_Figgs]

Hi all,

I'm a long time Photoshop user and have figured out tons of problems on my own but this one has me stumped.

Pressure sensitive brushes (shape dynamics and/or transfer) bearly show when I draw smaller like I usually do, but they do show if I draw larger and faster than usual, without pressing any harder. 

For example, I can draw a smiley face thats about 2-3 inches tall, but not one thats 1 inch tall. I can zoom in and draw the 1 inch face (at more of a 2-3 inch scale), but if I zoom out and try to draw the exact same smiley face the line is super faint or non existant. It doesnt matter how hard I push. If I try to draw a small face fast, it doesnt show, and oddly, if I draw a large face slowly It also doesn't show as well.

It seems to be working normally with non-pressure sensitive brushes. 

I've tried:

Using different brushes

Checked brush settings

Change cintique pen nib

Washing and drying the screen

Checked cintique pressure settings

Restarting Computer

Updating Photoshop

Reinstalling Photoshop

Please help me!
