There's some flickering on the light and, it's exactly the opposite: IF we were trying to eliminate entirely, the performances would collapse (every single light would need to be sorted against eyepoint distance at every frame) so, it has to stay like that, I don't find it very disturbing.
Thanks to the fact we offer a freely downloadable Trial, anyone can decide on the scenery before purchasing it. The are no limitations in the Trial version, except it doesn't work for more than 5 minutes at time, but otherwise it's exactly like the purchased version so, please, don't purchase it hoping that something you believe is a "problem" will go away, only because the scenery will be purchased.
