I've been trying out the new demo on a few different machines, both virtual and, uh, not, and so far I've only gotten the game to start when there is a floating-point unit installed (or support built in to the CPU). Otherwise the game hangs forever on "Loading assets" (it doesn't even draw the empty progress bar).
I don't know if you intended for an FPU to be a requirement or not; it's a perfectly reasonable requirement if so. But it isn't listed in the documentation here, so I thought I'd make sure this was a known thing.
Thanks!
