The new version comes with a so called "glow shader", whose purpose is to display a glow halo around the vectors. This shader is optional (because not all 3D cards support OpenGL 2.0 or more), and it is highly user-customisable.
When modifying these user settings, the display performances could be impacted (depending on the window size and the 3D card used, for instance). Also, the visual rendering will vary from one system to another, depending on the monitor attributes (LCD or CRT, brightness, contrast, etc...).
I'd like to bundle several predefined settings (what I call "profiles"), for the users to chose, depending on their preferences.
That's why I'd need some of you to run the emulator on your computer(s) and monitor(s), tell me what profile is good/bad in their opinion (both visually and performance wise). If you feel like it, you could also create your very own profiles (the emulator comes with an embedded editor) and send them back.
With these pieces of information gathered, I can hopefully have a good idea of what is the most user-adapted default settings, and what profiles I should include in the final bundle.
Here are a few pictures of the shader parameters editor:
The beta will be Windows only, and should be available in a couple of days. If you're willing to help, please drop me a line.
