EDIT #1 : Anyone that is having this issue - To force opengl, add to steam launch options "-force-opengl https://support.steampowered.com/kb_article.php?ref=5623-QOSV-5250 Hey everyone! So we have had a few Linux users have some graphical/launch issues. Our engine supports 64-bit Ubuntu 12.04 or newer. Any other version of Linux may have some undesirable results. We apologize for the limitation - but we really wanted to have Linux as an option. :) Gratefully, Eric As always you can contact us through the Steam discussion boards or contact@enlightenedgames.com
