Certain games such as Psychonauts (from Humble Bundle V) require S3 texture compression. As the algorithms are patented by S3 and cannot be licensed for use in Fedora, S3TC cannot be enabled by default in Fedora.

This means that Psychonauts etc cannot be run on a stock Fedora install.

If you live in a country where the patents are unenforcable, or you simply do not care about opening yourself to legal issues of this type, the RPM Fusion repository carries an open source implementation of S3TC in the libtxc_dxtn package.

Here is how to install it:

su -c 'yum localinstall --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm'

su -c 'yum install libtxc_dxtn'

On a x86_64 system, you might also need to install the 32-bit package:

su -c 'yum install libtxc_dxtn.i686'

Then launch the game as normal, and it should work fine!

If software patent issues like this really annoy you, then you might want to consider making a donation to organisations such as the EFF (https://www.eff.org/) that lobby against restrictions on what we can do with the computers we own.
