Hey,
I have Witcher 2 in the Docker (Linux Container). I have installed the GraphicDriver from Nvidia but with the glxinfo my Graphiccard have no DirectRendering. When this Problem is Solve i can other Games from GoG.com take in the Linux Container. From the experimentel i found out that the Perfomance is not to slow.

best greets

Hello,
after 2 Days excessive gaming and experimental prompt hacking. Witcher2 works without perfomance loss in the LXC-Container. I have create a Ubuntu trusty Version from lxc repro. Over login in the SSH with xforwarding and install Nvidia driver. All Libs from x386 install in the Container and portable to another machine ;D
