What’s new in version 2

Sim Daltonism 2 is so much faster than the previous version. It was rebuilt using the code from Red Stripe and now leverages your graphic card using OpenGL to make the filter faster than ever. You can now watch video throught the filter window if you want. Try it!

There is a new “transparent” window mode that lets you see underneath the filter window and even click through it.

That new “transparent” mode is the default, but Sim Daltonism can also follow the pointer instead if that’s what you want, like in the previous versions. When following the mouse, there is no longer any pyramid of doom where the filter window became visible inside of itself when moving the pointer near it.

There is also a setting now to adjust the refresh rate if you wish to save energy, or increase it even further to reduce the lag.

Sim Daltonism is now open source. Come take a look and contribute code if you like.

With version 2, Sim Daltonism is launching on iOS too.
