How do I install S3TC?

Question

I recently installed steam on ubuntu 12.10 and when i try to load tf2 this error appears: "Required OPenGL extension "GL_EXT_texture_compression_s3tc" is not supported. Please install s3tc texture support

Answer 1

you can try the trick described in this question, open a terminal and before running steam force the load of the extension so:

force_s3tc_enable=true steam

This if steam is the command from the terminal to run it ;)
