Brush Stroke Lag - V 1.7.2.471

[Tobias.VFX]

When using the brush or erase tool with any brush for the former choice, there is a significant lag in the stroke even when stabilization is turned off.  I use an XP-Pen 15.6 Pro with latest driver.  I cannot replicate this problem in other software.  Just happens in Affinity Photo as far as I can tell.

Just a quick note to report that this problem persists even with "high precision" turned off in the preferences of AP.

Hey Tobias,

Do you get this lag if you turn off Windows Ink?

Hi Chris,

Yes.  I just tested that out. There's about a 2 ms delay in the stroke no matter what brush I use.  Not sure if this is within "normal" tolerance but it makes drawing and painting by hand really awkward.

Your machine is really good. Yet... I don't have the lag....I have wacom, a classic, no screen, but other users with XPs don't have a lag, it seems. Something going on.

I have noticed  (but my machine is very low, in the extreme lower limit, in yours it might not count, at all) that brushes (besides, due to my machine, never working well with larger brushes than 300 / 400px) with (double click on a brush to change these settings) too low value of spacing, or hardness set to zero or low value (that is, max smoothness on contours) , or, heavy brush textures (in my crapPC... any textured brush diminishes performance), I've noticed all that can affect lag. A so called "round basic" (for some reason it best works starting from that one) brush, no texture, generous dots-spacing value, higher hardness value, is *way* more performing than the fancy brushes. Of course, it shouldn't be so (but one shouldn't be running Photo with a 11 year old machine) .

Not being right now able to visualize how would be a 2ms lag ...I have never measured that.

Then, leave it ON...seems is way more accurate with it, for brushes and lasso selection tool.

Is it me, or this was in another thread, with more posts and a video?...or maybe is from another user....

I've checked this with our XP Pen 12 and I get no delay at all. It doesn't matter if High Precision is off or on for me either.

These are my settings for the XP Pen 12:

This actually helped a great deal.  I missed that the XP-Pen dialogue had a toggle for Windows Ink that seems to be independent of the system settings.  Turning this off helped a lot.  I've messed with a select set of brushes as well but didn't notice too much of a big difference.  That's probably because my machine is really powerful.  I imagine someone would notice a greater different with a lower spec machine.

That's good news. 

I have it on good authority that we plan on revisiting Windows Ink compatibility in the future. We usually recommend turning off Windows Ink because of the conflicts it can cause but in an ideal world, this should not have happened.
