I started writing this late last year, and finally uploading parts of it. Currently, doesn't work, but doesn't crash either. Enable it via the NOVUS_USE_NEW_RENDERER environment variable. The goal is to use the game's own shaders instead of creating our own, it's lacking support for buffers with actual data in them and constants so while it "works" nothing is displayed on screen yet.
