@mo-g Did you see that GPU 3D rendering is being worked on and even working quite well for radeon cards (though not yet merged/in testable state)? Vulkan lavapipe software rendering is working on Haiku - #356 by X512
There is also progress with multi-head setup. And I think Axel (or someone else?) was working on a secure keystore, but I may be wrong there.
Also: I think there is a working VNC server for haiku already.
