game log and system specs in zip file
Issue happens on Ubuntu 16.04 using oibaf PPA (https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers) game doesn't start on AMD gpu. Before last updates (at least a month ago) it worked without issues.
Here are my system specs and logs from game, although I think there are no error logs until game is loaded which doesn't happen (tested by removing log file and running game, no new log was generated).
