Paint.net 4.1.5 released with performance improvements

The developer of the image editor Paint.net released version 4.1.5 of the application for Microsoft's Windows operating system today.

The new version of Paint.net is available on the Microsoft Store and as a Win32 program that users can download from the official project website.

Paint.net users who run the program already on their devices should receive update notifications when they run the program the next time. A click on Settings > Updates > Check Now runs a manual check for updates right away; Paint.net should pick up the new version and install it when that is done.

Paint.net 4.1.5. features performance improvements. The last version of the application improved application start significantly and it seems that work on improving performance of the application continues in this version of the program.

The developer of Paint.net added support for CPU instruction sets to the application which improves rendering performance by up to 50%

Optimized a portion of the rendering engine for newer CPU instruction sets (SSE2, SSSE3, AVX2). Depending on zoom level, CPU type, and other factors, rendering throughput has been improved by 10-50%.

Whether you will see improvements in this regard depends on the processor of the computer the image editor is run on, the zoom level, and other unnamed factors.

Rotate operations should be near instant in the new version next to that. You can rotate any image that you loaded in the image editor either by selecting Image and then one of the Rotate options, or via the shortcuts Ctrl-H, Ctrl-G, and Ctrl-J.

I ran a couple of tests with 10 Megabyte images in PNG and JPG format, and rotate did indeed process these instantly.

Image -> Rotate should now complete almost instantly.

Last but not least, Paint.net 4.1.5 includes optimizations that effect plugins may benefit from. Performance of these plugins should improve in the new version.

Some performance optimizations for code that uses the indexers on the Surface class, which should improve effect plugin performance.

Paint.net 4.1.5 includes a number of fixes next to that which you can check out on the roadmap; at least one crash issue fixed in the Store version.

We followed Paint.net's development for a long time. Our first review dates back to 2009, and the program has received numerous updates since that time.
