PS 22.4.3 performance lags

[Eugene154A]

1. Brush tool works too slow.

2. "Liquify" tool freezes, when such parameters are:

+ Image has more than 6 MPx;

+ Brush size is bigger than 2000 px

+ more than two operations.

Same here but with my way of working mostly shown as:

1) Pen lag. Anchor points show up late, sometimes seconds late
