Substance Painter 11.1.0 pen lagging

[xenoox]

Hello. Since version 11.1.0 I noticed that pen performance is much worse compared to version 11.0.3 (tested both in identical scenario). While on a new file it not as obvious, when complexity increaseses pen strokes with Windows Ink enabled are very unresponsive. Turning Windows Ink off or using mouse for painting makes the strokes smooth again (losing pen pressure in return). This is not the case with 11.0.3 where brush strokes are responsive regardless of Windows Ink status.

Same Issue here, confing XP Pen 24 artist Pro. Drives me crazy. Not trouble at all with previous versions. Passing OK, without window ink activated on xp pen driver board, but the brush react with no sensivity at all.

"good" in a way to here that its not just kamvas then. 

My pc isnt as beefy as the above but its no slouch either.

I noticed its lags just after a few layers in the stack, really nothing heavy ... and winink on of course for the sensitivity. 

Its completely fine without winink and with the mouse. Maybe its a vulcan / nvidia thing? But I got the latest gfx drivers so who knows.

11.1.0 version of painter is broken with wacom pen, mouse is fine but try the same stroke with pen, Painter lags out and freezes for a few seconds. Only fix is to disable Windows Ink but then that disables pressure settings.

Confirmed this is ONLY happening with new version of Painter. Every other program has both pen and pressure settings without lag of any kind.

The same thing happens with Xencelabs and Wacom — brush strokes update very slowly, even in a relatively simple file. If I paint with a mouse, everything is fine. What’s more, the issue didn’t appear immediately after updating Substance Painter, but some time later in a file I had been working on for a long time.
