1) Does the game run normally when installed via GoG? I ask because as everyone here is acutely aware, this game was notorious for its buggyness.

2) What exactly does nglide do? Is it better graphically to run the game using nglide over OpenGL solely for higher resolution support?

3) Was SiN ever open sourced? The Quake 2 engine, upon which SiN runs, was open sourced over 15 years ago.

4) Are there any other obscure settings that need to be tweaked to get SiN working correctly?
