Testing how each sim responds across multiple cores (MFC driver override should prevent ITBM 3. 0 from working, but I've also turned OFF the ITBM 3.0 service to be sure). This doesn't seem to impact P3D V4.3 at all, but CPU distribution for X-Plane is relatively low across cores ... this might be related to how X-Plane 11 operates on GPU thread optimization setting (via NCP)?
