After updating to Fedora 21, all 32 bits 3D games fail to run. Steam warns with this message at initialization:
OpenGL GLX context is not using direct rendering, which may cause performance problems. For more information visit https://support.steampowered.com/kb_article.php?ref=9938-EYZB-7457.

Anyone has a clue about how to fix this? Thank you.
