Starting in 2010 I made the first attempts to get Auteria running on 64bit Linux. Now 13 years later I made it. 

Auteria is based on the Torque Game Engine designed last century. It was not so difficult to get it compiled on 64bit but to get it run stable , was. The base engine used a lot of 32bit assembler and optimized pointer stuff which did not very good match 64bit. Thank you to the Torque2D and Torque3D developer who did the 64bit patches which helped me a lot, finally. I love programming and it's hard challenges so I made it possible. Auteria runs in my testing stable on Windows, Linux and FreeBSD.
