I've had Painter 2020 installed for some time, but only just got around to using it. I used to use Painter a lot (I have been a beta tester for it way in the past), have had it since Painter 8 - anyway. However, for me there is a very annoying lag between changing brushes/tools. I've tested my other versions installed 2017-2019 and whilst they have a little pause, it's not the 2-3 second gap that version 2020 has. This is very distracting using the keyboard short cuts B and N to go between the brush and the eraser. It really disrupts the process.
This is incredibly annoying and makes me want to give Painter up for good. I've seen a few other posts about a switch lag (not version 2020 I note), and the only solution was to reinstall Windows 10. Which I am NOT going to do. My graphics card does not have AVX2, but as I'm only trying to use simple brushes I don't think this should have any affect. I've tried all the tweaks I can, but with no effect.
Any advice, or suggestions?
No suggestions or help, alas, but I'm on a new machine (with old hard drive and operating system from my previous PC) and the specs exceed requirements. There's still a lag between eraser and brush, and that brush was first introduced in 2011. The lag is probably a lot less than on my old PC, but it's still there I'm afraid!
i noticed the delay/lag at brush switching gets bigger if you switch between brushes located in different libraries. a way to avoid the delay or shorten it might be to only switch between brushes that are located in the same library, for example only use brushes in "Painter 2018 Brushes".
if your work flow relies on brushes from different libraries it might be best to make a new custom library and save all your frequently used brushes in there.
this is true, but I'm not sure if brush eraser tool data is tied to any specific brush libraries.
I've ran into the brush/eraser tool switch lag several times in earlier painter versions (I think painter 2018 was the worst, and I don't remember it that much in painter 2020 demo), but iirc it used to appear over time and didn't affect fresh workspaces that much. I don't remember if there was ever any logic behind the bug - it seemed pretty random, like many of painters issues are.
ah right, the eraser tool. i have no clue if its tied to a library, i never use it.
i usually use one of the erasers from the eraser brush category, i don't know if you can set hotkeys for particular brushes but in case you use one of those wacom pens that have a extra eraser tip on the other end - i think they work just like the regular pen tip so you can assign a eraser brush to the eraser tip and painter will switch between them automatically if you turn your pen.
there might still be a tiny delay but its far from the 2-3 seconds green loading bar you get when you switch between libraries.
it is just the eraser tool - it basically sometimes works worse than switching between an eraser variant in one brush library and every other painting tool in another if you've never ran into this issue just to give an idea.
and it is indeed much faster to just pin an eraser brush variant somewhere on a custom panel (which defeats the purpose of having a separate all-purpose eraser on a hotkey in its current broken state.)
