Brush Tool massive lag with a mouse

[wojciechm56529697]

Hi.

After installing all my favorite software on a new Dell Precision 5520 (i7, Nvidia Quadro M1200, 16Gb Ram, Win10x64)I noticed this weird behavior of the Brush Tool:

I'm kind of used to weird stuff when it comes to Wacom Tablets, but a mouse? First time. It was never a problem before.

Therefore, I have no idea how to approach this.

My graphics processor acceleration is enabled in Photoshop, besides this is a small resolution file, that even a i3 should have no problem with.

Windows Ink is on, and besides, toggling it off and on doesn't change the problem.

Brush is a simple oval with no special effects, this should be a breeze for this system.

Yet it lags as if it was 30k px x 20k px.

Any ideas?

Using: Adobe Photoshop Version: 19.1.0 20180116.r.238 2018/01/16: 1153018 x64 Latest NVidia Drivers: 388.16

Here's my full System Info dump.

Have you checked the Smoothing level, it may be set to high

Also the latest version of Photoshop is 19.1.2 so may be worth updating

THANK YOU!

I honestly had no idea about that setting.

When was this introduced?

Been working with digi-art since PS 7.0 and never noticed that.

You're welcome,

That feature was only introduced in CC2018
