Thanks, such a port would certainly be much appreciated. More and more systems are 64bit nowadays. By now, I've gotten rid of anything 32bit on my system, which has been a problem 2 years ago. Package maintainers of all linux distributions could integrate it more easily into their systems. Recently, we linux users get nice improvements on the graphics driver side too. I've copied the game dir to my windows partition; On the first launch, I had the same error. I then deleted the cfg and ini files and relaunched the updater, which downloaded/updated one additional dll file. This solved the issue in Windows (or probably only deleting the ini file solved it, don't know). On gentoo, grabbing a lib from somewhere might work but that is quite a hack and works around the good build/packaging system. The proper way would be to compile it myself so that it integrates properly. I think that would require to set up a 32bit chroot just for that. A bit overkill just for playing a game ;-) Besides, it might not only be a problem with the libtxc_dxtn, but with other missing dependencies too. Thanks for your help, but for the moment I'll stick to booting Windows for playing this game. Hibernating and dual-booting is a nice and cheap solution to this problem. I'm looking forward to your x64 port, though. It could make the game more future-proof and avoid memory limits.
