I have been running spotting dot testing for a few days, typically with 200 aircraft at a time. Performance has been fine until this update just dropped, now it has cratered.
Hundreds of non-moving ground units don't seem to cause the same performance drop, and facing away from the moving air units doesn't stop the CPU from getting clogged up. So I assume this is the AI pathfinding / AI thread clog bug again.
Please try replaying this at 1080p.
