REX Simulations proudly announces Atmos CORE, a groundbreaking real-time atmospheric, weather, and environmental engine for Microsoft Flight Simulator 2024. Unlike surface-level filters, Atmos CORE injects changes directly into the simulator’s core engine, delivering physically based realism, instant visual feedback, and complete creative control. Its modular interface, Weather, Atmosphere, and Enviro, lets pilots craft or modify live weather, sculpt atmospheric layers, fine-tune lighting and color, and simulate authentic particulate effects like haze, dust, and fog. With robust preset management, cloud-based sharing, and an upgrade discount for existing REX Atmos 2020 owners, Atmos CORE sets a new standard in immersion and customization.
