I'd like to know where this patch is too. If something has changed such as the patch was integrated into the main download, that should be communicated with customers too. I've looked in the " gog downloader links", and near the bottom there is listed:

"Witcher 2: Assassins Of Kings, The - Enhanced Edition - Linux - patch:"

But there is no link beneath it.

So is there a game patch, or not?
