--- Comment #29 from Todor todormailbox-wine@yahoo.com --- Tested the UT3 installation and gameplay with Wine 3.0 stable under Ubuntu 16.04 LTS and it works without issues.
I had to install UT3 in 32-bit mode though - with WINEARCH=win32. I also had to use winetricks to install Adobe Flash, Shockwave and Internet Explorer 8 to avoid issues with the installer.
I am using AMD open-source GPU stack. The game was installed from the retailed DVD version (not Steam). I applied all patches, including TitanPack and Patch 5 (which is download only).
No other tricks or registry changes were applied - the game now plays out of the box.
Thanks to the Wine team for finally resolving all the issues with UT3.
