: Essential for professional "dome" setups or multi-screen cockpit configurations where multiple systems run concurrently to create a seamless field of view. SimOperator : Includes an Instructor Operator System (IOS)
If you add more than 400 scenery entries, the UI may fail to load. Workaround: Use the scenery.cfg editor manually or update to v4.1. AMD GPU Flicker: Early v4 builds had driver conflicts with AMD Radeon cards (specifically the Vega architecture). Solution: Roll back drivers to Adrenalin 18.5.2 or switch to NVIDIA. The "Battery Drain" Bug: In Professional Plus, leaving the master battery switch on while refueling would cause an infinite electrical drain simulation. Lockheed Martin addressed this in a subsequent hotfix, but 4.0.23.21468 still has this "feature" which adds a layer of genuine realism for emergency procedure training.
