--- Comment #1 from Tyson Tan <tyson...@mail.com> --- I have tested Krita 4.1.0 on two latest Macbooks today, but none of them are working well despite of their relatively high hardware specs. I don't know whether we have plan to optimize Krita on macOS in the future, but since the performance was alarmingly bad, I felt the need to report the detail as well. ### TEST ################ Macbook (Retina, 12-inch, 2017), Intel Core m3-7Y32 (1.2Ghz) 8GB 1866Mhz RAM. Macbook Pro (13-inch, 2017, 2 Thunderbolt 3 ports), Intel core i5-7360U (2.3Ghz) 8GB 2133Mhz RAM. Both Macbooks were running macOS High Sierra 10.13.2. Krita 4.1.0.dmg Wacom Intuos S Gen 3 CTL-4100 with driver 6.3.30-2 installed. ### SYMPTOMS ################ Brush preset "Basic-6_detail" is lagging behind, the drawing speed is even worse than Celeron N3450 and APUs under Windows 10. Long and quick strokes crawls far behind for seconds before they can be finished, it's simply unusable. Brush preset "Basic-5_size" and other less resource intense presets are more responsive, but the tablet signal is clearly being dropped heavily, resulting in undesired straight lines when drawing curves. Krita 4.1.0's release notes said it had fixed this problem, but it appeared to be otherwise during my tests. Reminder: Core m3-6Y30 under Windows 10 can handle these without breaking a sweat. ### MORE ################ I've also tested Pentium N4200 8GB under Windows 10. It was as slow as its brother Celeron N3450. The only difference being its burst frequency of 2.5Ghz, but it appeared to be irrelevant during the test. The result made me suspect optimization issues even more. -- You are receiving this mail because: You are watching all bug changes.
