In case this helps the engineers at ED, we run a dedicated server using the Dedicated Server software provided by ED. The software is running on a Dell PowerEdge R710 on ESXi 6.5 as a virtual machine.
I was unable to replicate the issue with non-aggressive AIs in some brief tests, in each test (Client F-14B (radar on) vs High AI MiG-29, Client F-5 (radar off) vs High AI MiG-21bis) the AI was aggressive towards the player immediately at a spawn range of ~10 miles with no aggressive actions from the player (F-14B had the MiG-29A on TWS, tried with a plane with radar off to confirm if it was viewing radar as aggression).
The server does not have a dedicated GPU; HOWEVER, as a virtual machine the EXSi host "tells" the virtual machine (our server, running on Windows 10 Enterprise x64) that it has a GPU but a very weak one (4MB VRAM).
Hope that helps the ED engineering team.
