Some people are having trouble accessing the new patch to 1.04 through GOG. Since it was requested by a few I have uploaded it to a file sharing site so you would be able to download it.

Some people are experiencing crashes related to GPU and more performance problems than they did with 1.03.

So it may be a good idea to backup your current installation before patching the game so you are able to revert back to 1.03 if you encounter these issues.

Here is the link to the 1.04 patch. The file size is 273MB and requires something along the lines of 512MB of HDD space to install.

Enjoy!!
