Descent 3: Piccu Engine is a new open source build focused on quality-of-life improvements

Thanks to Descent 3 being officially open source, developers can do almost anything with it now and this has given rise to the Descent 3: Piccu Engine.

Forked from the open source Descent 3 game engine the Descent 3: Piccu Engine, it includes "almost every change from InjectD3, among many more". You might think, well why not submit to the original open source project? But this is the benefit of open source isn't it! People can do whatever changes they want.

This includes enhancements like:

• Centered window mode.
• Scaling in window and fullscreen mode.
• Fullscreen which does not change desktop settings (multi adapter support forthcoming).
• New mouse code.
• Adjustable FOV, with automatic expansion for widescreen.
• Missing features in OpenGL restored, including specular highlights and the ability to control mipmapping.
• Cockpit actually works in widescreen, unlike InjectD3.
• Faster iteration when many missions are present.
• Smoother UI (FPS limit raised to 60).
• OpenAL sound system with no crackling and environment reverb support.
• Many bugfixes.

Currently though according to the GitHub page this version of the code is only set up for Windows, but the developer hopes "to change this shortly".

You do need a copy of the game to run it which you can get from GOG and Steam.
