Sorry for taking 152 days to respond, mine runs at 90fps as well on a Rift CV1, rx 570 and an r 1600x, so the crashes certainly aren't due to the specs
I haven't tryed it for it's intended use yet, but I have a issue were it trys to "interface" with my Rift and boots up the Oculus softare. (It doesn't show anything in VR though, it just boots it like it is trying to)
there are 2 right click functions (deleting and cansiling) and you can change them in the controls. i personaly preper the simplistic option, but you can set the cansle build function to be something else if you want
slight problem. the energy production bar for the wind farms is based on the average for wind turbines are, not the actual amount they are producing at the moment
