Hi, my first post here! Thanks for all the good work, I'm liking AR5 a lot.

The Custom Brush is very laggy for me, I'm just playing with the built in presets for now, like the Bristle 6 Blend, but they all seem to crawl and don't feel very usable at all to me personally. I'm painting on a small canvas 800x800px just for testing. Every other tool is fine, even the Oil Brush at 500% doesn't lag for me.

Specs

AR 5.0.1
Win 10 x64
Intuos Pro
i7 6700 - 3.8GHz
16GB RAM - 2600MHz

Any way I can speed it up?
