Please add a feature flag for falling snow. The purpose is to allow some to increase FPS by disabling falling snow in scenes. I believe this is the only ambient weather, however, would include rain if that exists as well. Configuration of particles in the general form are not enough. Some particles are more equal than others. The absence of weather effects is less likely to break suspension of disbelief and immersion than say the hobbling of fire, sparks, expositions, etc.
