Title says it all. Only one core is being used by Painter, no matter the multicore settings (real watercolor brushes are taking forever to diffuse!). I've used the default of 4 cores (half of my iMac 2017's 8 cores). I've also tried 8 cores. No difference. I've also tried resetting to Painter factory defaults. No help. Painter 2018 works fine with multicores on the same machine. OS version is 10.13.6 (the latest).
Is this happening to anyone else?
I’m running 10.13. I have preferences set to 4 cores, and that works as expected. Choosing 8 cores does not work.
Interesting. I've tried all multicore settings, from 2-8, and none of them work. At this point, Painter 2019 is an expensive paper weight for me. One good side effect: this is encouraging me to work more seriously with Rebelle 3.
Multi-core can be disabled for each individual brush, so I'm wondering if the brush has it disabled. To check can you go to the general panel (Cmd+B) and see if "Multicore" is checked for the brush you are using?
Thanks, that was the first thing I checked. I mentioned in another thread that I discovered multiple cores are, in fact, being used. But they are being severely throttled (so the sum of all cores in use is only 100% of one core). Seems like something Corel could have easily overlooked in their performance optimizations.
I have exactly the same problem. It is too bad. I could ill afford the upgrade and as you say it is an expensive paperweight. Painter 2018 is working fine on 8 cores so I have gone back to that for the time being. Rebelle 3 is definitely becoming more attractive! I am on a 12 core 2010 Mac Pro 64GB ram and a GTX10170.
