AndréF Posted October 5, 2020 Share Posted October 5, 2020 Hello, the stroke is very laggy on some brushes (gouaches…) on my Windows machines. What is strange is that given the same canvas resolution on my iPad pro (2018) and MacMini (2018) there is no perceptible lag with se same brushes (& sizes). Is there missing optimization on the Windows version or this a limitation of the renderer on Windows (compared to Metal) ?

Staff Chris B Posted October 16, 2020 Staff Share Posted October 16, 2020 Hey AndréF, Windows has hardware acceleration in the beta version so it's worth giving that a shot.
