Hello! I apologize if this question has already been answered.

I am using Krita on a basic dell laptop which has 64x windows on it and 8 gigs of ram. I didn't see anything on the performance requirements about needing a better graphics card or anything like that but it is a new but low end computer with this processor: Intel(R) Core(TM) i3-7100 CPU @ 2.4GHz 2.4 GHz.

My question is when I'm painting what I think are reasonably or even low sized files, say 11x17 300dpi, the lag on the brushes is incredible. Especially if I'm using any of the blending brushes in any significant size. It can take up to five minutes to render a single stroke.

Is my laptop just incapable of handling files this large or do I have something wrong with the settings? I have the canvas graphics acceleration off and otherwise I'm using default settings. Thank you for any answers!

The minimum system requirements are always a headache because we can only really note at which point Krita will be completely and utterly unusable. Systems that go above it are not guaranteed to work smoothly. We can in fact not even determine the line at which krita works smoothly because performance and especially perception of it can wildly differ depending on operating system, hardware, security software, and the person using it. This on top of the fact that Krita is a content-creation program, and those, unlike, say, video games will always have the bar getting raised over the years.

Your processor might be a bit on the weak side, and the color smudge brush is indeed the slowest of all the brush engines. It might be an idea to go to f5 and increase the spacing on the brush tip, or not use large brush sizes for brushes like those. Krita doesn't use the graphics card much, because it is a 2d painting application, we mostly use it for showing the canvas.

Is there any reason why you have the canvas graphics acceleration off? If you have it off the graphics card wouldn't even matter at all. It will take a chunk of CPU processing power to draw the canvas, which could have been used for applying the brush strokes otherwise.

Mostly only because I saw a video saying turning it off would help. Should I turn it back on? If it's just "your computer can't handle files that size" I'll deal with it for a while until I can afford something better, but anything I can do to get a little better performance until then would be very helpful.

Thank you I will try that. It is what it is I suppose!
