Hello,
This is a bit unusual behavior, as the TDS GTNXi XPlane runs utilizing external processes, the performance should not be impacted at all, due to this technology there should be minimal to no performance drop when utilizing the TDS GTNXi XPlane.
Can you please test the same scenario with the freeware KingAir C90B:
forums.x-plane.org/files/file/92114-king-air-c90b-evo-gnsgtn-blackhawk-xp12
And let us know of the performance, as the C90B utilizes a different (aircraft side) drawing method than the AirfoilLabs KingAir 350.
Please state your full system specs.
In addition, as a test, you can try lowering the X-Plane 12 graphics settings a bit so there will be a little room available for each PC Trainer process.
