Quoting: rkfgI've become curious about one thing: if Vulkan provides such a low level access to hardware, what will happen if an app (a game usually) starts to misbehave? I read Vulkan has very little validation in favor of speed. Does that mean that a buggy game could crash the entire Xorg or freeze the driver? A user-space segfault usually leads to crashing the program but not the entire system (and Xorg/desktop for many people is the system), but if invalid data goes into the kernel space or the Xorg driver and crashes there because of that... I suppose it would be bad. Kernel panic for the module and Xorg crash in case of the Xorg driver.

Is it any better with OpenGL? It's direct access too. A misbehaving game/driver can easily freeze a system. You can sometimes switch to a console to kill the game, but often it is not possible. You could still ssh into the box if you have another system available, but how many users can do it?

You lucky Truck Sim fans. No hopes for Train Simulator or Farming Simulator on Linux any soon now. :( Train Simulator is one of few games that make me keep my Windows partition.
DTG (the publisher of Train Simulator) is working on an Unreal Engine 4 version of their game but any questions about SteamOS/Linux support receive noncommittal responses.
