I recently bought Corel Painter 2019 in the Humble Bundle thing and I absolutely adore it! The only thing that keeps me from enjoying it fully is that there's a small (3-5 second) delay between hotkeys. Is there any setting I could change to help it run just a little faster?
Okay! Well, I did all the steps you suggested and I can say it does work a little bit faster although not perfect. My three top brushes as of now are Flat Color, Glazing Acrylic 2 and Dull Cont. If I could just get those to load smoothly, I'd be so happy!
