Brush looks blocky/low resolution when painting textures (Pic included) I'm sure this is something silly I'm doing wrong here but I can't find a solution at all. My texture is 2048x2048 and I'm trying to paint details on it. 

When I draw the brush looks blocky/pixelated though. The stroke looks like it has a low resolution. The smaller the radius the worse it looks and painting side to side looks better than when painting up and down.

Here is a picture:


If someone could try to help me out here, that would be great.
in texture paint mode go to your left panel and go to options and deselect occlude in project paint
