Krita without a doubt is an awesome drawing software but there is one problem which has been bugging me for a while, my stylus strokes are kind of slow on krita (I’m using Wacom Cintiq 16)
This lag also happens when I’m using Photoshop, Clipstudio Paint, Fire Alpaca, Medibang.
On the other hand, I don’t face any problems and the stylus strokes are super responsive on Sketchbook Pro and Paint Tool Sai.
Also I don’t have any smoothing enabled on Krita. I can technically draw on Krita but the mini lag keeps bothering me and forces me to draw slower than I’m used to, any suggestions to reduce the brush lag?
Maybe you try the speed-optimized-bundle @RamonM published a few days ago? It’s current a small WIP-Bundle, but these brushes are fast as lightning and fun to use, at least for me.
Thanks for the recommendation but they seem to be same speed like the default brushes. It always feels like Krita has some inbuilt stabilization feature which tries to slow down the stroke but I’m not able to figure out what is causing that (since I don’t have smoothing enabled)
Your CPU is 4x more powerful than mine and I have 16GB of DDR2 RAM.
(I have two CPUs but that won’t be an advantage for painting.)
I see lag if I paint with Chalk Dirty base at a brush size of 200px but not if I use Dry Speckle Bristles-GM at 250px.
Does it help if you have Instant Preview enabled?
My tests were with Instant Preview disabled.
Another possibility is that you’re running other demanding applications at the same time, e.g YouTube music videos, or you have a very active anti-virus running.
That’s all I can think of.
Another thing: When I was testing Skechbook Pro and Krita with Mouse still Sketchbook Pro felt more responsive even with mouse and Krita seemed to slow down my mouse strokes as well (I have a feeling the lag/smoothing what I’m experiencing in Krita might be an inbuilt feature?)
Then, everybody must have this lag, and that is not the case, there must be another issue on your side that’s not figured out at the moment. Unfortunately, often the search for that particular cause/issue, is like the hunt after the needle in the haystack!
I’ve spent way too much time trying to reduce input lag in Krita, but some of the first basic steps you can take is if you have an Nvidia graphics card, try setting these two options for Krita in the control panel:
Next, if you want a true representation of how fast your tablet is responding, open Settings->configure->tablet->open tablet tester and doodle around on there. If it’s still laggy on there, that’s going to be your driver or tablet.
The settings you mentioned on Nvidia only slightly changed the stroke’s speed (I think)
But in Tablet Tester the strokes are MUCH faster and better!
Edit: Spoke too soon (had forgotten to apply the settings of Nvidia) it does speed up the stroke but not as fast as the tablet tester, which is the speed I would like.
Unfortunately that’s a very, very complicated problem to overcome with the more complex tools because of the inherent flaws of QT’s frame buffering and event management. Unless the devs acknowledge that there’s a problem and that artists do in fact notice it, like yourself, Krita will always be laggy.
Have you set a “Brush Cursor”? it is off by default.
“Brush Cursor Icon” will be as responsive as your mouse, it is more suit for line art in my opinion.
Krita’s “brush outline” have a little lag behind the system cursor, and will be much noticeable when doing line sketching.
In 5.1 we can assign a shortcut toggle “brush outline”, making it off and leave “brush cursor” for inking / line sketching , and “brush outline” turn on while painting.
If the lag happens on most software like you mentioned then it is not just krita. No need to mess around with nvidia settings etc. Can you also show a small recording of the lag. Just to see if it is same for us and we are ignoring it.
