Brush Size Cursor performance not smooth (H16 Premium)


Is there a way to make drawing performance with brush when enabling Brush Size Cursor smoother?
Its so laggy and jerky, like jumping from 60fps to 30fps. Very noticable and not usable at all…

I want to see the current selected brush size but not loose the performance just by enabling Brush Size Cursor.

Also, when Brush size cursor is ON, can it still be on while drawing? it disappears when drawing and shows up when not drawing…

btw, panning (hold space bar and move mouse) is also jerky and not smooth…

Im using dual monitor with several windows from harmony scattered on the second screen.
1: 2560x1440 (main)
2: 1920x1080

tried with one monitor (1) only just to see if the second one was too much but no difference…

any way to fix this?

Did you figure out how to fix this ?

i got the same issue when i just switched to Brush Size Cursor but its only when im using my wacom intous pro not when im using my mouse.

The wacom intous pro was working super smooth without the Brush Size Cursor on and is working super smooth in photoshop, illustrator, animate and toonboom harmoy without the Brush Size Cursor on.

the issue here is the same it feels like the fps dropped for the cursor when i switched to Brush Size Cursor.
