Either on :
Macpro 5.1 4 core XEON 2,93 GHZ GPU RADEON 580 Go
or MacBook Pro I7 4 core 2,3 ghz Bi GPU intero iris pro / Nvidia GT 750
"esquisse aquarelle réaliste" (in french) 12 BRUSH IN REAL WATERCOLOR
show circles when applying (pink color)
On Mac Pro, same gear, bootcamp windows 10,
the brush is acting well. (beige)
On the Mac side, same with newer tryout version of painter,
either with Nvidia or AMDcard.
If anyone could please test it on Mac with previous system to find out if this is a Catalina issue ?
Well just find out other apple compatibility issue with other softwares.
Painstrorm studio use Open GL if I am not wrong, but apple stopped at open GL 1.2 (to promote Metal).
i have a GPU 4.3 compatible, Ati RX 580 , but it only use 1.2 on macOS.
It is sad to use a windows bootcamp partition for paintstorm studio and Corel Painter because of apple too much early choices.
On windows, Paintstorm studio GPU accelerated brushes are truly really accelerated and lighting fast.
Not like Corel Painter Gpu accelerated brushes, that are 5 % 10 % accelerated, at most.
I was running Painter 2018 on OS high Sierra worked just fine, updated to Catalina and Painter 2021. Performance went down the toilet on both 2018 and 2021. I am considering rebooting and updating to Mojave, can't find anyone complaining about 2021s performance on Mojave so I guess thats a positive. Both apple and Corel are so unhelpful I suspect both are at fault Catalina was a very bad update and Corel always seem out of their depth with apple tech. I don't want to resort to bootcamp windows and the funny thing is Corel boast improved performance on Mac with 2021.
English not my first language but I found your post helpful ty
hi. I have no performance issue.
Something would be helpful for me if you are going back to Mojave.
Please try the 2019 brush library real watercolor brush I listed (Watercolor sketch, if my translate is right, 12th brush in the 2019 real watercolor list) and tell if it is working weird either.
I have not decided wether to downgrade to Mojave as of yet but I did try the watercolour brush in 2021 and it makes the same stamp look in your example, a wonderful coffee stain look just for us Mac uses. If you could be so kind help me out by making a new image 2000x2000 300ppi. in oils select detail oil brush open brush controls change type to glazing and try crosshatching or printing your name, if it preforms ok turn pressure on in glazing and opacity, have a draw let me know if it lags. On Monday ill phone apple and Corel one last time then reboot and ill try your water brush again.
Hi it does not lag From what see.
What model is your Mac (+ cpu / Gpu ?) please ?.
Just a bet Do you use Wacom drivers ? They could be not catalina ready. There was a lot of issue with those drivers in the past.
I use an iPad as graphic tablet with software Astropad and / or Hardware Luna so I don't know for Wacom.
