Just recently the brushes have developed a huge lag. There's no problem drawing/painting in Photoshop CC so it's not the tablet.
I'm running Painter 2015 v18.104.22.1688 on iMac 27 16GB ram/OSX 10.9.5. Wacom intuos medium size w/current driver.
If anyone has an idea why this is suddenly happening please respond.
If something has suddenly changed (for the worse) and it persists I'd consider doing a reset by holding shift on launch. It could be that a workspace has become corrupted and therefore a reset will correct it. Make sure you copy and save all of your custom brushes, palettes, etc. so that you can import them into the reset Painter.
No luck JoeC. Brushes are still lagging.
But thanks for the input.
I have been having the same problem. I bought painter 2015 not too long ago and at first it was all fine, but just opened it today and my brushes were experiencing serious lag issues. I thought maybe something was wrong with the Mac. I restarted it, cleaned it up a bit and nothing. Opened up Photoshop CC, no problems, nothing. I went over to my PC and opened Painter 2015, nothing. Works perfectly fine.
The only thing I can think of is that it's something to do with the Mac. I know it's not a memory issue or usage problem as I have nothing on this laptop. I only use it for school. It's practically brand new. I prefer PCs over Macs so I am usually never on it. So I have no idea what could be causing it honestly. Maybe there's a recent update conflict or something. I don't know. I am hoping someone figures it out because I am out of ideas as to what the problem is and the lag is horrible.
Oh and on a side note: I still have Painter X3 on here too. I opened it up and it was experiencing the same brush lag issue. So I am seriously thinking it might be a Painter/Mac problem maybe. I could be wrong (more than likely I am), but thought that was something worth pointing out.
Edit: I tried uninstalling it and reinstalling it. It did nothing. Still having brush lag. Decided to add that it in as it was something I just tried.
Check what your Cores usage is set to in Preferences. Set them low, like at one or two. Possibly it's having a resource conflict with some other program working in the background. Though I'm only guessing (I'm on Windows). Painter will still work fine with low cores (often better with less resorces).
It was the Enhanced Ghost Brush cursor. Mac OS X 10.9.5 doesn't like it for some reason.
Switching to any other cursor type fixes the problem.
But hopefully Corel will patch Painter as EGB is useful with tilt enabled brushes.
