This is an attempt to find a Solution for a After Effects Brush Tool Problem

Using the most up to date version of After effects.

Anytime I go to use the Brush tool, and Paint in my Selected layer, and Making sure I double click It and everything 

The Brush seems to leave much lag behind my pen and leaves very inconsistent and buggy straight strokes, when trying to attempt to make smooth curves.

Any help would be appreciated, Thanks
