Ok I had exactly the same problem I thought I was disabling it but still seeing aircraft. So I did the following and it got rid of all traffic.
- Settings-General-Online-Aircraft Traffic Type = Off (if it is set to Off already, scroll through until it says Off again)
- Then click Save and Back
- Settings-General-Graphics-Air Traffic = Off (if it is set to Off already, scroll through until it says Off again)
- Settings-General-Graphics-Traffic Airport Quality = Off (if it is set to Off already, scroll through until it says Off again)
- Then click Save and Back
- Settings-VR-VR Graphics-Air Traffic = Off (if it is set to Off already, scroll through until it says Off again)
- Settings- VR-VR Graphics-Traffic Airport Quality = Off (if it is set to Off already, scroll through until it says Off again)
- Then click Save and Back
Saving before moving to a new tab is key.
Hope this helps
