paint.NET lagging even on extremely small images


Recommended Posts

My Paint.NET is slow/laggy when trying to draw pixel by pixel lines or move the mouse around. This started after the last paint.net update. 

 

This is occuring even on TINY pictures (100x100 pixels) with no layers.

I am using a completely stock Paint.NET, no plugins

System:

Intel i5 4700k
Nvidia GTX970
16GB DDR3 RAM
Paint.NET installed on SATA SSD

Please try this:

 

Go to Settings - top right side of the canvas and click on the cog wheel :Settings:

Then uncheck the box Hardware accelerated rendering (GPU)

 

Hopefully that may help.  If not, please post back :)

Are you using a G-Sync monitor with you Nvidia card?

 

G-Sync windowed mode is known to cause all sorts of problems with everything, including Paint.NET.

Well it could be something you've changed in your NVIDIA control panel. I'd first look there for anything non-default.

 

The lag is likely not Paint.NET specific, and will probably happen in any other application with similar technology characteristics. Direct3D / Direct2D, runs in a window, in particular. MSPaint and Paint.NET are about as far apart, technologically, as is currently possible ... I would not compare them.
