The makers of The Witcher 2: Assassins of Kings Enhanced Edition from CD Project Red have made the game available on Steam for Linux, but they used a Wine-like wrapper to do the job. A native port is now in the works and that means more people will be able to play it.
Besides SIGGRAPH going on right now in Vancouver, Canada, over in Cologne, Germany right now is GDC Europe.
GDC Europe ran from August 11 and ends today in the wonderful German city of Kölsch beer and carnival. Leszek Godlewski of Nordic Games talked about advanced Linux game porting at one of the sessions during GDC Europe. Godlewski has made a name for himself with Linux game porting and is responsible for Linux game titles like Painkiller: Hell & Damnation. Leszek has talked in the past about lessons in porting games to Linux, a developer's perspective on Linux game porting, etc.
