I had the following error message on Linux Mint when trying to play a new game: This application requires either the GL_EXT_texture_compression_s3tc, or the GL_EXT_texture_compression_dxt1 + GL_ANGLE_texture_compression_dxt3 + GL_ANGLE_texture_compression_dxt5 OpenGL extensions. Please install S3TC texture support. Solved by installing the 32-bit libtxc as follows: sudo apt-get install libtxc-dxtn-s2tc0:i386
